摘要
A new type of DZ9000E Oxygen Gaseous HVOF system (GHVOF) is developed which can reduce the cost of coatings and increase the in-situ removability to adapt various working conditions. The whole system is economical,which enables the system to meet the requirement of spraying medium or low cost High Velocity Oxy-Fuel (HVOF) coatings for medium and small job shops. The deposited cermets coatings by the DZ9000E system have good performance with average microhardness HV0.2 of more than 1000 and the bond strength between coating and substrate of greater than 50MPa.

The whole system is economical, which enables the system to meet the requirement of spraying medium or low cost High Velocity Oxy-Fnel （HVOF） coatings for medium and small job shops. The deposited cermets coatings by the DZ9000E system have good performance with average microhardness HVo. 2 of more than 1 000and the bond strength between coating and substrate of greater than 50 MPa.
