产品名称：High velocity oxy-fuel spray (HVOF)

High velocity oxy-fuel flame spraying,also known as HVOF.The basic principle shown ain Figure 7,the basic principle of the process is similar to the traditional flame spraying,the difference is that the use of a supersonic lance,when spraying particle speed is much greater than the conventional flame sparying.The high velocity oxygen fuel flame spraying (HVOF) can use the fuel gas (such as :propane,acetylene,hydrogen)can also use a liquid fuel such as kerosene. HVOF coatings prepared with high-density,high bond strength,high hardness,excellent wear resistance,excellent corrosion resistance ,excellent poilshing,and has been widely used in the steam turbine prats,ball valves,Aviation lndustryand so on,material of choice.Widely used in the aerospace industry.
