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-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.
