钛合金材料具有比强度高，变形系数小，热强性、低温韧性、抗腐蚀性和焊接性能好等优点，被越来越多地用于飞机制造业。镀铬技术作为一种特殊过程在航空制造领域广泛应用，最常见的就是飞机起落架零件镀铬。目前，国内的起落架零件制造大多是在高强度钢表面镀铬，而钛合金零件镀铬的应用非常少见，主要是由于镀铬工艺属于特殊过程，其工艺质量受到诸多方面影响并且不易评定，况且钛合金材料刚刚兴起，国内对其镀铬工艺质量控制经验几乎为零。通过不断尝试研究，结合生产实际，将飞机起落架钛合金零件镀铬工艺流程细化，从材料、设备、人员、工艺和加工环境等方面进行控制，完善并优化了工艺条件，提高了加工效率，节约了制造成本，保证了工艺质量。

Titanium alloy material has high strength ratio,small deformation coefficient,hot strong resistance,low tem-perature toughness,corrosion resistance and good welding performance advantage.So it has been more and more used in the aircraft manufacturing.As a kind of special process,chromium plating technology is widely used in the field of aviation manufacturing,the most common is the aircraft landing gear parts chromium plating.At present,the domestic landing gear parts manufacturing is mostly in the high strength steel surface chromium plating,and it is hard to see the application of tita-nium alloy chromium plating,because that the chrome plating process is a kind of special process,the quality is affected by many aspects and it’s hard to evaluate.Besides,the titanium alloy material has just been widely used,we almost have no experience about how to control the quality during titanium alloy parts chromium plating.The factory has tried and re-searched again and again,combined with production practice,elaborated the landing gear titanium alloy parts chromium plating process,controlled the quality from the material,equipment,people,technology and the processing environment of chrome plating,so as to optimize the process conditions,improve the machining efficiency,reduce the manufacturing cost and ensure the process quality.
