Preparing thin solid film on the metal surface is one of the important methods to improve the metalproperties.
在金属表面加工薄膜层是提高材料性能的重要途径之一。

There are many factors which affect the wear of metals, such as load, slide velocity, environmental medium and temperature, metalproperties and so on.
影响金属材料磨损的因素很多，如载荷、滑动速度、环境介质、温度、材料的性质等。

Once the part starts to solidify small dendrites of solid material form in the part. During this time metalproperties are being determined, and internal stresses are being generated.
