6 Hard materials for wear parts Hard materials in general and hard metals in particular offer a series of interesting properties for all applications where maximum wear resistance is required. In practical applications, wear parts are usually influenced by various interdependent factors: high pressure, high temperature, use of abrasive or aggressive media, machining of hard materials. These are only some examples of criteria causing wear, which hard materials or hard metals have to be resistant to. The powder-metallurgical production of CERATIZIT wear parts enables tailor-made wear resistance of the material. This is what makes CERATIZIT hard materials and hard metals indispensable when it comes to decisively increasing the service life of highly stressed components. Ever more powerful machines, facilities and machining methods create daily new challenges for the CERATIZIT development engineers. Our development projects are characterised by close cooperation with customers as well as a joint search for solutions to application problems. Causes of wear Abrasion Cutting with water-jet and abrasive additives at a pressure of 4000 bar (approx. 500g sand/min.) Temperature Cutting of molten glass. Temperature 1,250°C Pressure/mechanical stress Tool for the synthesis of CBN and PCD pressure during operation: 72,000 bar
