FAQ

Here are answers to some common questions about titanium coated diamond powder:

What is the coating process for applying the titanium layer?

Chemical vapor deposition (CVD) is typically used to deposit the titanium coating uniformly onto the diamond microparticles or nanoparticles. This allows controlled coating thicknesses.

How strong is the bonding between the titanium layer and diamond core?

There is extremely strong carbide bonding between the titanium coating and diamond powder. This ensures excellent adhesion and durability.

What industries use titanium coated diamond powder?

Automotive, aerospace, electronics, construction, medical, and oil/gas industries utilize this material for grinding, polishing, drilling, cutting tools, engine parts, and a variety of friction and wear applications.

What particle size titanium coated diamond is best for improving tool life?

Generally nano and micro-sized particles exhibit substantial improvements to bonding strength, wear resistance and extending operational lifetimes of diamond tools, while still retaining nanoscale diamond sharpness.

Is the coating uniform on all diamond particle sizes?

Advanced chemical vapor deposition (CVD) processes allow high quality coatings across a wide range of diamond powders, from nanodiamond through macrosized particles. Coating consistency determines overall performance.

Can any metal be used to coat diamond powder?

Titanium offers an optimal combination of coating adhesion, corrosion protection, thermal resistance, and alteration of material properties like friction and conductivity. Other metals like tungsten or chromium are also used in some diamond coating applications.

What are typical prices for titanium coated diamond abrasives?

Prices vary widely based on quality, customization, particle size and volume – from around $7 per carat for larger Ti coated macrodiamond powder through $600 per carat for precision nanodiamond grades.

Závěr

Závěrem, titanium coated diamond powder retains the extreme hardness of diamond particles while gaining corrosion resistance, thermal stability, tailored frictional behavior, conductivity, and bonding properties from the nanothickness titanium metal coating. Combining the two materials creates a unique composite that expands the range of applications and improves performance of diamond tools and parts across demanding industrial sectors. With robust CVD coating processes ensuring uniform, durable coatings on particles ranging from nanodiamond through macrosized powders, titanium coated diamond abrasives will continue gaining traction in high precision, difficult machining and friction scenarios requiring diamond’s mechanical capabilities at higher working temperatures, speeds, and lifetimes.
