Research on the Influence of Two Kinds of Quenching Oils on the Heat Treatment Quality of Leaf Springs (Part 2)
传统的淬火油，如石油底物、矿油基润滑油，可能含有沉积物、氧化物或杂质，所以它们可能会堵塞热处理设备中的喷嘴或管道，从而影响其工艺性能和用户满意度。 许多科学家认为聚碳酸酯（PC）是更优质的淬火油，该产品具有消防和抗热性。在PC淬火油中未发现明显的残留物，因此可靠性更高，故障率也更低。此外，PC还具有优秀......

The basic principle of phosphating - pretreatment before phosphating
Phosphating is a process in which a series of salts are applied to metal surfaces to improve their rust protection and painted surface adhesion. In order for phosphating to be effective, proper surface preparation must take place prior to its application. This includes ridding the metal surfaces o......
