Gas Quenching Small Components Paul Stratton1 (1.BOC, Sheffield, UK) 摘要:Gas quenching is an environmentally friendly and effective way of quenching components. However it has not been possible to apply it to small components because of the difficulties of jigging. A method of gas quenching such small components is described in which they are levitated in a confined gas stream. The method......
