SinoDiam Surface-Engineered Industrial Diamond
01 / Technical Overview
Diamond Surface Engineering for Abrasive Tool Manufacturing
Different coatings and surface treatments address different interfaces. The right choice depends on the diamond crystal, bond system, process conditions and required tool behavior.
Coated and surface-treated diamond refers to industrial diamond abrasives whose external surface has been modified for a defined toolmaking requirement. The treatment can introduce a metallic or carbide-based layer, or modify the original diamond crystal surface without intentionally adding a coating.
These treatments may influence how abrasive particles interact with a tool matrix, including wettability, chemical interfaces, mechanical retention and the response to manufacturing processes. Benefits must be confirmed within the actual tool system.
Mechanical Grain Engagement
Nickel coating texture or a surface-etched crystal may influence mechanical interaction with a suitable abrasive-tool bond.
Application-Oriented Selection
Consider resin curing, metal sintering, ceramic firing, electroplating and brazing as different manufacturing environments.
Coated Diamond vs. Surface-Etched Diamond
Ti, N30, N56 and TiC are specified by the material added to or formed on the diamond surface. Surface-Etched Diamond is different: it modifies the original crystal surface without intentionally depositing a new metallic layer. The correct choice depends on the intended bond and tool process.

04 / Bond Compatibility
Choose the Coating Around Your Bond System
Metal, resin, ceramic, hybrid and electroplated abrasive tools impose different requirements on the diamond grain and its surface treatment.
Metal-Bond Abrasive Tools
Titanium and TiC coatings are relevant evaluation candidates for selected metal-bond systems. Matrix chemistry, pressing conditions, sintering temperature and abrasive retention must be assessed together.
Resin-Bond Grinding Wheels
Nickel-coated grades N30 and N56 are useful candidates when evaluating particle retention in suitable phenolic or polyimide resin formulations. Actual surface texture and resin interaction must be checked.
Ceramic / Vitrified Bonds
Selected coated grains may be evaluated, but ceramic firing can introduce different temperatures, atmospheres and chemical interactions from metal or resin processing. Grade-specific trials are required.
Electroplated Diamond Tools
Surface-etched grit may be evaluated where particle texture and cleanliness influence the deposited-metal interface. Plating bath chemistry, deposit thickness and grain exposure remain critical.
Hybrid-Bond Abrasives
Hybrid matrices combine different bond characteristics. N30, N56 or another treatment may be considered according to the complete matrix chemistry and manufacturing cycle.
Brazed Diamond Tools
Titanium-containing coatings can be considered in suitable brazing trials. Filler alloy, oxide condition, processing atmosphere and interfacial reaction determine compatibility.
Is One Diamond Coating Compatible with Every Bond?
No. Coating chemistry, morphology and manufacturing conditions determine suitability. A result obtained in a resin-bond wheel cannot automatically establish performance in a hot-pressed metal bond or high-temperature ceramic firing process.

06 / Material Selection Guide
How to Select the Right Diamond Surface Treatment
Begin with the workpiece and manufacturing route. Coating selection should follow the tool system, rather than a product-name or coating-percentage comparison.
Define the Workpiece
Specify concrete, stone, cemented carbide, technical ceramics, glass or another material. Include operating conditions and the intended cutting or grinding result.
Identify the Bond System
Confirm metal, resin, ceramic, hybrid or electroplated construction. Describe the curing, sintering, firing or plating process.
Specify the Diamond & Coating
Define base diamond grade, mesh size, coating material, nickel-content basis, TiC phase or etch texture as appropriate for the selected treatment.
Validate in the Finished Tool
Compare coated and uncoated abrasive under matched tool-manufacturing conditions. Evaluate grain retention, removal rate, matrix wear and cost per workpiece.

08 / Technical FAQ
Frequently Asked Questions — Coated Diamond
Common questions about coating materials, bond compatibility, diamond retention, mesh size and surface-treatment selection.
1. What is coated industrial diamond grit?
Coated industrial diamond grit is diamond abrasive
with an added or formed surface layer, such as
titanium, nickel or titanium carbide. Coatings
are evaluated for their interaction with an
abrasive-tool matrix and manufacturing process.
2. What is the difference between coated and surface-etched diamond?
Coated diamond has an additional metallic or
carbide-based surface layer. Surface-etched diamond
modifies the original diamond crystal texture
without intentionally adding a metallic layer.
These are different material technologies.
3. Which coating should I consider for metal-bond diamond tools?
Titanium and titanium carbide are relevant
candidates for selected metal-bond applications.
The appropriate treatment depends on matrix alloy,
base diamond grade, sintering or brazing process,
atmosphere and required grain retention.
4. Are nickel N30 and N56 interchangeable?
Not automatically. They belong to the nickel-coated
diamond family but may differ in nickel content,
surface texture and intended bond applications.
Compare measured specifications and tool-process
requirements before substitution.
5. What does N56 mean in nickel-coated diamond?
N56 is a coating-grade designation. In the broader
superabrasives industry, 56 wt% nickel-coated
diamond is a recognized category. The actual
SinoDiam nickel content and percentage reporting
basis must be confirmed using current documentation.
6. Why is spiny nickel surface texture important?
A textured nickel surface may create additional
mechanical engagement with suitable resin matrices.
The resulting retention depends on actual coating
morphology, coating-to-diamond adhesion,
resin chemistry and wheel manufacturing conditions.
7. Is titanium-coated diamond the same as TiC-coated diamond?
No. Titanium-coated diamond has a titanium-based
metallic surface layer, while TiC-coated diamond
specifies a titanium-carbide surface layer.
Interfacial carbide formation during processing
does not make the finished products automatically
equivalent.
8. Can coated diamond be used in resin-bond grinding wheels?
Nickel-coated diamond, including N30 and N56,
is an important evaluation option for selected
resin-bond grinding wheels. Compatibility depends
on resin chemistry, coating specifications,
curing conditions and the intended workpiece.
9. Is surface-etched diamond suitable for electroplated tools?
Surface-etched diamond may be evaluated in
selected electroplated tools, but the result
depends on particle cleanliness, surface
morphology, bath chemistry, deposition process
and the required abrasive exposure.
10. What diamond mesh sizes are available?
Historical SinoDiam product descriptions reference
325/400 mesh and coarser for some titanium-,
titanium carbide- and surface-etched products,
and 500/600 mesh and coarser for certain
nickel-coated products. Current size availability
must be verified for each treatment and base grade.
11. Does diamond coating guarantee longer tool life?
No. Finished-tool performance depends on the base
diamond, coating, bond composition, workpiece,
manufacturing process and operating conditions.
Any tool-life improvement requires matched
comparative trials.
12. Can a coating guarantee protection against oxidation or graphitization?
No universal protection guarantee can be made.
Coating continuity, chemistry, atmosphere,
temperature and exposure time influence
whether a protective effect is obtained.
Processing and operating conditions must
be evaluated separately.
13. How should I compare different coated diamond suppliers?
Compare equivalent base diamond grades and
particle-size fractions, coating composition,
content and measurement basis, surface morphology,
bond-system compatibility and current inspection
data. Validate performance in matched finished-tool
trials wherever possible.
14. What information is required for a quotation?
Provide the target workpiece, tool type,
bond system, manufacturing process,
diamond mesh size, base grit if known,
preferred treatment, coating specifications,
estimated quantity and delivery destination.
