对航空发动机产品大量使用的9310合金钢材料进行不同的氧化工艺试验,研究不同氧化工艺对氧化膜耐磨性能的影响.通过对外观、耐蚀性、厚度、耐磨能力的综合考察,得出结论:采用二次氧化法和添加了亚铁氰化钾的一次化学氧化法(氧化时间100 min)制备的氧化膜的耐磨性良好,相较于常规一次氧化法,氧化膜的耐磨性显著提高且其他性能优异.该方法解决了航空发动机产品在试车以后齿轮咬合面出现局部氧化膜破损的问题,提升了产品质量和使用寿命.
Study on the effect of oxidation process on the properties of 9310 alloy steel for aero-engine gears
Different oxidation process tests were carried out on the 9310 alloy steel materials,which is used in large quantities in aero-engine products,to study the influence of different oxidation processes on the wear resistance of the oxide film.Through the comprehensive examination of the appearance,corrosion resistance,thickness,wear resistance ability,it is concluded that the wear resistance of the oxide films prepared by the primary chemical oxidation method with the addition of potassium ferrocyanide(oxidation time of 100 minutes)and the secondary oxidation method is good,and compared with the conventional primary oxidation method,the wear resistance is significantly improved,and other properties are excellent.This experiment solves the problem of localized oxide film breakage on the occlusal surface of gears of aero-engine products after the testing,and improves the product quality and service life.
