“…Such differential thermal expansion is known to occur at temperatures of about 400°C, causing ruptures to occur in the diamond-to-diamond bonding, and resulting in the formation of cracks and chips in the PCD structure. Chipping and micro-cracking of cutting edges occur as a result [41][42][43].…”

This chapter first discusses the challenges with the tool material selection for machining of high-silicon aluminum-matrix composites. It is shown that the combination of a soft easy-to-adhere Al-matrix and highly abrasive particles limits the use of cemented carbide tools due to high rate of adhesion and abrasion wear. The issue becomes intolerable in high-speed machining applications. As a result, polycrystalline diamond (PCD) is slowly becoming a material of choice for such applications. The chapter presents the major research advances in PCD as a tool material. The wear mechanism of PCD is discussed at macro-and micro levels. A discussion on the need and a report on the progress in the development of thermal stable grades of PCD conclude the chapter.

“…Dynamic friction polishing (DFP) technology [10] is an abrasive-free process which utilizes the thermochemical reaction induced by frictional heating between diamond and catalytic metal plate rotating at a high peripheral speed (15-25 m=s) to polish single and polycrystalline diamond. DFP technology has the advantages of high material removal rate and simple experimental equipment.…”

Chemical vapor deposition (CVD) diamond film has high heat resistance, high thermal stability, and other excellent properties as nature single-crystalline diamond. The surface polishing, large size planarization, and high material removal rate of CVD diamond film are limited due to its special crystal structure and excellent physicochemical characteristics. Dynamic friction polishing (DFP) technology is a new and effective polishing method of diamond. In this paper, according to the theory of graphitization of diamond catalyzed by unpaired d electrons, two manganese-based alloys, Mn-Cu and Mn-Ni, are selected as polishing materials to achieve high quality and high efficiency polishing of diamond and verify the mechanism of DFP. Alloying polishing plates were prepared by mechanical alloying method and spark plasma sintering technology. The polishing results of Mn-Cu and Mn-Ni alloys were compared and analyzed through DFP experiments. The experimental results showed that since Mn-Ni alloy has more unpaired d electrons than Mn-Cu alloy, Mn-Ni alloy was more likely to form vacant rails and showed a higher material removal rate of CVD diamond film. The addition of Cu decreased the wear of polishing plate with the help of its lubrication action.
