Interaction of Composite Brazing Alloy Sn-Cu-Co-W with Diamond at Brazing of Diamond Abrasive Tools

It was researched the interaction of composite brazing alloy Sn-Cu-Co-W with surface of diamond during formation of a diamond-bearing layer on abrasive tool. It was determined the influence of the composite brazing alloy components on wetting of diamond grains and their subsequent retention in metal matrix. The prototypes of stone-machining routers were manufactured with use of the designed composite brazing alloy. Thickness of obtained diamond containing coating is even over the entire surface is 2 mm. Due to the high viscosity of the composite brazing alloy it is well retained on the contoured surface of the substrate including the vertical sections.
