新型活塞材料据报道，碳经过特殊加工后，可成为一种理想的活塞材料。这项技术是德国戴姆勒本茨·康采恩集团的研究成果。制造活赛的碳必须是非常纯净的．所采用的活塞毛坯是在烧结炉中大约烧制３个月，使其细粒结构的性能达到要求，再在保护气体中进行退火处理，就得到黑...
New Piston Materials It has been reported that carbon can be an ideal piston material after it has been specially machined. The technology is the result of research by the German company Daimler-Benz-Coszen. The carbon that makes a living must be very pure. The piston blank used in the sintering furnace is fired for about 3 months to make it meet the requirements of the performance of fine-grained structure, and then in the protective gas annealing treatment, you get black ...
