现代机器的寿命比较短促,过上十几、二十年就“衰老”了。为了扭转这种局面,人们绞尽脑汁,想了许多办法。冶金学家和金属学家们在六十几种金属元素中调配来、调配去,炼出了种类繁多的高强度的制造机器的材料。工程技术人员们挖空心思,创造了一系列使另件长寿之法,诸如辊子滚压、表面淬火、渗碳、氮化、氰化等表面强化法,都是行之有效的良方。而喷弹强化则是后起之秀。它是一种全新的强化工艺,在一般教科书里还找不到它的详细记载。
The life span of modern machines is relatively short, and they are “aged” after a decade or two. To reverse this situation, people are racking their brains and thinking of many ways. Metallurgists and metallologists have deployed and deployed more than six dozen metal elements to produce a wide variety of high-strength manufacturing machine materials. The engineers and technicians have thought out a lot and created a series of methods for longevity, such as roller rolling, surface hardening, carburizing, nitriding, cyanidation, and other surface strengthening methods, which are effective methods. Jet reinforcement is a rising star. It is a brand-new enhancement process, and its detailed records cannot be found in general textbooks.
