内燃机第一道活塞环镀上硬铬后,能使活塞环的性能大大提高。因此,目前镀铬环已作为许多发动机的标准配件应用。在高性能的发动机里,由于对活塞环有更高要求,而硬铬镀层仍不能满足要求。在这种情况下,采用火焰喷钼层能使其进一步得到改善(见图1)。但当 After the first piston ring of the internal combustion engine is plated with hard chromium, the performance of the piston ring can be greatly improved. Therefore, the current chrome ring has been used as a standard accessory for many engines. In high-performance engines, hard chrome plating does not meet the requirements due to higher requirements on piston rings. In this case, the use of flame spray molybdenum layer can make it further improved (see Figure 1). But when
