| Abstract: | Fe547B alloy powder spray melted coating was sprayed on high temperature and high pressure valve sealant made from 12Cr1MoV steel with one-step method spraying process of oxyacetylene flame and fluxing compound.The spraying process and the hardness, age-hardening characteristic, thermal durability and scratching resistant of spray melting lager were studied. The results have proved that healing up of cracking on high temperature and high pressure valve sealant by spraying Fe547B alloy powder is certainly feasible. |
