DE3615127A1 - Pressure sintering method of manufacturing The invention relates to a pressure sintering method of manufacturing metal-bonded diamond tools, in particular for hand-operated filing machines. The pressure sintering method is carried out in moulds made of steels, having good tempering properties, at a temperature of approximately 600 DEG C. The powder mixture is metered and the moulding ram cross-sections are dimensioned and their surface
DLC in all forms is extremely hard. Depending on which form is applied, DLC is as hard, or even harder, than natural diamond. In ta-C form, DLC typically measures between 5000-9000HV. Other forms range from 1000-4000HV. The high hardness of DLC coatings reduces the likelihood of hard particle penetration into tools or parts.
Diamond Grit - an overview ScienceDirect TopicsJ.S. Konstanty, in Advances in Powder Metallurgy, 2013. Cobalt substitutes. Until the early 1990s, the economical viability of the toolmaking process had been mostly affected by a high cost of diamond grits and, to a lesser extent, graphite moulds, whereas the contribution of cobalt and cobalt-based matrix powders had remained at an acceptable level. The forthcoming price cuts in the diamond
