Abstract: The present invention relates to a method of making a cemented carbide or a cermet body comprising the steps of first forming a powder blend comprising powders forming hard constituents and metal binder. The powder blend is then subjected to a mixing operation using a non-contact mixer wherein acoustic waves achieving resonance conditions to form a mixed powder blend and then
then the mould is cleaned and kept ready for next casting. The same method is followed to get the metal matrix composites of different weight percentage of the reinforcing phase. The composition of samples is given in the table 2. Table 2. Composition of samples Sample No. Tungsten Carbide (WC) (%) Molybdenum Disulphide (MoS 2) (%) 1 - - 2 2 4
tungsten carbide square tool bits Advantage of tungsten carbide square tool bits 1.stable and reliable quality. Product information of tungsten carbide square tool bits 1,Dimensions of existing mould: 1). is a professional tungsten carbide manufacturer with ten years'' experience in Zhuzhou City.
Tungsten carbide can exist in two phases; WC and W 2 C, and have a hardness of 2000 – 2700 HV. Tungsten carbide powders come as monocristalline WC with a carbon content ≈ 6, 1% or eutectic WC/W 2 C with a carbon content ≈4% as seen in a carbon – tungsten phase diagram. Figure 1 shows the tungsten-rich part of the binary W-C equilibrium

Bit design method. The bit geometry and cutting structure engineering method of Bentson has since 1956 been the root from which most roller-cone bit design methods have been designed .Although modern engineering techniques and tools have advanced dramatically from those used in 1956, Bentson’s method is the heritage of modern design and continues to be useful for background explanation.
