摘要：

研究了加热时间、喷射高度、喷射压力及高温防氧化涂层对40CrNi4Mo1V炮钢高压射流除鳞的影响。研究结果表明，除鳞宽度随着喷射高度的降低而减少，喷射高度由130 mm降低至110 mm，除鳞宽度减少约11 mm，喷射压力对除鳞宽度的影响并不显著。当喷射高度降低至110 mm时，相邻射流重叠区域基本消失。提高喷射压力、降低喷射高度可以增加射流打击力，在实验条件下，喷射压力高于30 MPa时，试样片表面氧化铁鳞清除干净。40CrNi4Mo1V炮钢高温下形成(Fe、Cr)氧化物相和(Fe、Ni、Mo)合金相盘错的氧化铁鳞，其与基体的结合力高，清除难度大，氧化铁鳞相连接基体中生成大量FexOy-CrxOy内生氧化质点。涂覆高温防氧化涂层的试样，除鳞后表面形成低于10 μm的极薄FexOy层，基体内部存在极少量内生氧化质点且深度不超过40 μm。

The effects of heating time, jet height, jet pressure and high-temperature antioxidant coating on high-pressure jet descaling of 40CrNi4Mo1V gun steel were investigated. The research results show that the descaling width decreases with the decreasing of jet height, the jet height is reduced from 130 mm to 110 mm, the descaling width is reduced by about 11 mm, and the effect of jet pressure on the descaling width is not significant. When the jet height is reduced to 110 mm, the overlapping region of neighboring jets basically disappears. With the increasing of jet pressure and the decreasing of jet height can increase the jet striking force. Under the experimental conditions, the jet pressure exceeds 30 MPa resulting in the effective removal of iron oxide scales from the specimen surface. The 40CrNi4Mo1V gun steel forms iron oxide scales at high temperatures, in which the (Fe, Cr) oxide phase and the (Fe, Ni, Mo) alloy phase are intertwined. The adhesion between iron oxide scales and substrate is notably strong, which complicates the removal of iron oxide scales from the substrate, resulting in the formation of a substantial number of FexOy-CrxOy endogenous oxidized particles. For the specimen coated with a high-temperature anti-oxidation coating, an extremely thin FexOy layer with the thickness of less than 10 μm is formed on the surface after descaling. There are extremely small amounts of endogenous oxidation particles inside the matrix, and the depth of these particles does not exceed 40 μm.
