At the beginning of the 21st century, a surfacing repair technology imported from Russia and converted into independent intellectual property rights has been successfully applied in railway locomotive and many industrial fields, showing its strong vitality and broad application prospects.

Surfacing repair technology is to add a kind of surfacing powder material into the lubricating oil carrier to produce a very hard and smooth surfacing layer on the worn surface of metal parts in the process of friction movement, so as to improve the wear and improve the service life.

By using surfacing repair technology, not only can the metal worn surface of various machines be repaired in situ without disassembly, but also the surface of new parts can be strengthened pretreatment. At present, although this technology has not been widely used in cement industry, it can be predicted that with the continuous improvement of surfacing repair technology and its further application in cement industry, it will play a huge role in promoting the continuous improvement of cement production equipment, energy saving, electricity saving and other aspects. What need to point out finally is, although all sorts of wear-resisting technology has very good use effect, but their oneself also can exist a few limitation inevitably. There is not a kind of wear-resisting material technology on the world is omnipotent, cement enterprise should choose the wear-resisting material technology that suits him most according to his actual situation.
