·This cemented carbide was a type of ceramic SiC material and shattered existing preconceptions by exhibiting corrosion resistance close to that of SiC Strength was about two to three times that of SiC in the to range while hardness was HRA or about the same as SiC Mechanical seals in process pumps are exposed to
·The type of material obtained by forming a coating layer of certain thickness on the surface of a cemented carbide matrix using physical and chemical methods which possesses protective or special functional properties There are three commonly used coating processes 1 chemical vapor deposition CVD deposition temperature 850 1100 °C and coating thickness
·The unique property of cemented carbide is thatitoffersasafer andmoredependable solution than any other known material to one of the toughest problems which engineers have to con tend with reliability Reliability is often a problem of wear Wear resistance is the most outstanding feature of cemented carbide Cemented carbide can also
·The most industrially used gradient cemented carbide is the γ phase free gradient The main benefit of γ phase free gradients thickness 10 30 μm is the increased toughness in the surface layer In cemented carbides coated with CVD it is necessary to prevent the propagation of thermal cracks formed in the coating during the cooling step of
This edition has a new chapter on crystallographic textures and their influence more on aluminum lithium alloys and cemented carbide tools new information on copper and nickel rewritten chapters on other non ferrous metals and low carbon steels new discussions of compact graphite and austempered ductile iron and an updated table on metal prices
