1·So screw, nut design is based on wear resistance.
因此螺杆、螺母的设计依据是耐磨性。
2·For carbide glass ceramics stone precious stones and other heavy-load cutting grinding wear resistance.
用于硬质合金、玻璃、陶瓷、石材、宝石等重负荷切割、磨削耐磨性好。
3·For carbide, glass, ceramics, stone, precious stones and other heavy-load cutting, grinding wear resistance.
用于硬质合金、玻璃、陶瓷、石材、宝石等重负荷切割、磨削耐磨性好。
4·Pump cover material with steel ZG230-450 more, can also be used ductile iron, the latter two materials contrast of wear resistance and hardness and heat resistance to be because the former.
泵体、泵盖的材质采用铸钢ZG230-450的较多，也可以采用球墨铸铁材质，两种材质对比后者的耐磨性和硬度以及耐温性要因为前者。
5·Sputtering is now widely applied on cutting tools, forming tools, injection molding tools, and common tools such as punches and dies, to increase wear resistance and service life.
现在反应溅射法已被广泛应用于切削刀具、成型工具、注射模具和诸如冲头和冲模之类的通用器具，以增强其耐磨性和使用寿命。
