Comparing with the traditional Oxygen and Kerosene HVOF system (LHVOF), the development of the DZ9000E Oxygen Gaseous HVOF system (GHVOF) is emphasizing on reduction of the cost of coatings and removability of in-situ application under various working conditions. DZ9000E hand-held spraying gun is assembled with dual-valve handle, ON/OFF switches for powder feed and compressing and cooling valve, which can provide portable and simple operation mode for users. The whole system is economical, which makes the system to meet the requirement of spraying middle or low cost HVOF coatings for middle and small job shops. The deposited cermets coatings by application of DZ9000E system has good performance with the average micro hardness is over HV0.2900 and the bond strength between coating and substrate is over 50MPa. Keywords: removable mode, low cost, GHVOF spraying, coating performance
