MBS*Si2 Coated Diamonds – Clear the Way for High Content Fe Bonds

Substantial Reduction in Bond Raw Material Cost Finally Possible

Through an innovative proprietary coating process, silicon carbide coated MBS Si2 diamonds from Diamond Innovations make long awaited improvements in bond raw material cost possible. Toolmakers are now able to reduce their costs significantly by replacing more cobalt with iron in their bonding systems. A replacement of 70% of expensive Co powders with lower cost Fe powders is feasible by utilizing Diamond Innovations MBS Si2 in the bond matrix.

Best Bet in All Atmospheric Conditions

Past attempts to use non or low Co bonds with high iron content were mostly constrained by the high reaction rates of diamond with iron. Now MBS diamond Si2 coatings enhance crystal retention extremely effectively in high Fe bonds. The Si2 coating is strongly bonded, achieving a powerful adhesion to the diamond surface.

MBS Si2 diamonds allow easier sintering control and improved bond flexibility. When manufacturing harder bonds, higher temperatures become necessary. Si2 coating effectively protects the diamond crystal from destructive high temperature reactions. If a non-oxidizing atmosphere is used in the sintering process, bonds with high iron content can also be processed with much higher temperatures without significant loss of diamond grade.

Unmatched Bond Retention

By adhesion with the high Fe bond matrix, unmatched bond retention is reached. The result significantly reduces pull-out rates and enhances free cutting properties, even in demanding applications. Every crystal may now be used to its full working potential, prolonging tool life and delivering high productivity rates.
