HM separation equipment for wear-resistant coatings in nature and mining production, there is a lot of friction and wear and tear. According to incomplete statistics ceramic coating technology, one-third to one-half of the world's energy consumption in friction ceramic coating manufacturers, while 80% of the mechanical parts fail because of wear. Objective To investigate the friction and wear that to some extent it is to control friction and reduce wear. In heavy medium coal fields, equipment wear and tear is quite large, especially in two-phase flow from coal, heavy media pulverized coal and water erosion caused by the equipment. In this type of wear, the interaction between solid and liquid is a ceramic coating, movement of solids under the action of water, while the presence of solid particles in turn have an impact on the flow turbulence. Due to the complexity of the problem, there are many people in the industry recognize their differences, there is no complete study of the theory of discourse. At present, a large number of measured data is combined, analyzed and explored the distribution of two-phase flow velocity, resistance characteristics, solid particle concentration distribution and so on. But the reliability of the device itself, at present, although made some research, but is still in the exploratory stage. Over the years, at home and abroad in order to improve the wear resistance of coal preparation equipment and piping, extending its life, done a lot of experiments, also achieved some results. Our country has reached thousands of yuan annually by corrosion and economic losses caused by wear and tear. Modern works on material performance requirements often multiple in nature, corrosion and wear are the main cause of failure of materials and components. Beijing wear and Technology Co., Ltd. specializes in thermal spray process, with the international advanced supersonic jet flame spraying, supersonic arc sprayed ceramic coating sales, plasma, flame spray equipment such as thermal spraying and welding rolls and other equipment. According to the different needs of customers spraying stainless steel, aluminum, zinc, copper, molybdenum, nickel and nickel-based alloys, wire, cobalt-based, iron, copper and aluminum alloy powder, chromium carbide, zirconia, titanium, tungsten carbide like composite powder material. And superb technology means, to wear the workpiece, corrosion, high temperature, thermal shock anti-oxidation, etc., all kinds of thermal spray coating properties have been successfully used in the preparation of all walks of life. The main characteristics of thermal spray technology is divided into the following categories: .1. Wear: 2. High temperature and oxidation: 3. Anti-corrosion coating: 4. Conductive coating or insulating coating: 5. Restore the size coating: 6.
