| Abstract: |
| In this paper, the oxy-acetylene flame alloying powder spraying technology was used to strengthen the wear-proof surface of slurry valve. Through the research on the effect of spraying process on the quality of overlay, the method to improve the spraying quality was proposed. It is proved that spraying overlay may obviously prolong the life time of slurry valve, and may be widely used in the manufacturing of valves. |
