在以磨损和腐蚀为主要危险的场合,等离子表面硬化工艺中的几项新进展,可以为寻求更为经久耐用的零件提供途径。例如,最近的进步有:使等离子喷焊能用于地方很小,难于接近的场合;一种新系列的喷焊合金粉末比传统的碳化钨粉末更为耐用;等离子喷焊,特别是应用钴的代用合金时,能够把钴的需求量从每个零件几磅减少到几克。这样,在性能没有任何下降的情况下,使成本得以降低。
In wear and corrosion as the main danger of the occasion, the plasma surface hardening process in several new developments, can find ways to provide more durable parts. Recent developments, for example, include the use of plasma spray for small, inaccessible locations; a new line of spray-alloy powders that are more durable than conventional tungsten carbide powders; plasma spray welding, particularly the use of cobalt Of the replacement alloy, can reduce the demand for cobalt from a few pounds per part to several grams. In this way, the cost can be reduced without any performance degradation.
