摘要
NSK 开发的新型钛合金抗蚀性极佳且不含有毒成分,比以往所用的防磁材料如铍青铜合金更加安全可靠。钛合金的化学成分和热处理条件经过改进后,可使其硬度达到500HV 左右,NSK 已将这种新型材料应用在轴承的生产制造上。这种防磁、抗蚀轴承主要应用于包括电子束装置和半导体制造设备等许多场合。
NSK has developed highly corrosion-resistant titanium alloy rolling bearings.Titanium alloy is a safer ma- terial for the environment and personnel than prior non-magnetic bearing material,such as beryllium copper alloy. The hardness of this titanium alloy is about 500HV,which was achieved by optimizing the chemical composition of the alloy and heat treatment conditions.As a result of the higher hardness,in comparison to ordinary titanium alloy, NSK's newly developed titanium alloy can be utilized tbr bearings.Applications of non-magnetic and corrosion-re- sistant titanium alloy bearings include electron beam equipment and semiconductor manufacturing devices.
