Yoong Manufacture of Nickel-Ceramic Composite Membranes in Agitated Electroless Plating Baths Bulasara et al.   According to the previous experimental studies on the [2][3] ceramic composite armors [7, 8], in the wear test, the performance parameters of the bit and the machining technological parameters have been determined, as listed in Table 1, along with the number of holes that each bit have accomplished until scrapped. 3.

Advanced Aluminum Powder Metallurgy Alloys and Composites / nitride cutting tools are needed for effective ma- chining. The high-cost conventional machining of MMCs can be eliminated by near-net shape manufacturing or by noncontact machining tech- niques such as laser processing (Ref 32) and abrasive waterjet cutting (Ref 33). In this work, grinding test was performed in terms of machining parameters, such as grinding speed, feed rate, etc., in order to study effect of ultrasonic vibration in grinding. The design of experiment (DOE) approach was used for an optimal condition of ultrasonic assisted grinding, which can minimize the grinding forces. In DOE, ultrasonic amplitude power, feed rate, and rotation speed of Cited by: 2.

Silicon carbide of the regular type is used for grinding cast iron and nonferrous metals, and a special high purity type is used occasionally for the rough grinding of cemented carbides.

Diamond. wheels, however, are preferable and are always used for cemented carbide finish grinding. The grain size generally varies over a narrow range only. The abrasive wear of a series of diamond and tungsten carbide (WC)-based metal matrix composites has been examined using both low stress scratching abrasion (rubber wheel) and high stress grinding.
