超音速喷涂设备


超音速火焰是利用丙烷、丙烯等碳氢系燃气或氢气燃气与高压氧气在燃烧室内,或在特殊的喷嘴中燃烧产生的高温、高速燃烧焰流,燃烧焰流速度可达5马赫(1500m/s)以上。通常被称作HVOF(High-velocityoxygen-fuel)。将粉末轴向送进该火焰,可以将喷涂粒子加热至熔化或半熔化状态,并加速到高达300-500m/s,甚至更高的速度,从而获得结合强度高、致密的高质量的涂层。超音速火焰速度很高,但温度相对较低,对于WC-Co系硬质合金,可以有效地抑制WC在喷涂过程中的分解,涂层不仅结合强度高,且致密,耐磨损性能优越,其耐磨损性能大幅度超过等离子喷涂层,与爆炸喷涂层相当,也超过了点镀硬铬层、喷熔层,应用极其广泛。
