Research On The Heat Treatment Quality Management Of Aviation Faster

It is well known that titanium alloy fastener heat treatment process is changing the material organization,From α state to α+β.Then the fastener products will obtain the necessary performance,and ensure that safe use on the aircraft,so it is important manufacturing process of titanium alloy fastener.For the reason that everyone of the fastener’s heat treatment quality characteristics(structure and properties)can’t be completely verified by the subsequent inspect and test,and if the heat treatment appear quality problem,it will cause large negative impact and economic losses,so the heat treatment process is identified as a "special process",Need to operate the various aspects,and all the factors involved in quality control.The pillar business is research and produce titanium alloy fasteners for the 109 department of Beijing aeronautical manufacturing technology research Institute involving heat treatment process.The whole process of heat treatment quality management can’t effectively prevent the occurrence of quality problems.Due to the equipment and facilities,technical and skilled personnel,product technology,production process control,operation regulations and production management level,all has weak link in the titanium alloy fastener heat treatment,and heat treatment process related to the most important performance requirements of the fasteners.Therefore,it is very important to control the heat processing quality,especially for the mass production of fasteners quality being stable,reliable and controllable through a comprehensive quality management.According to the comprehensive quality management related theory and the domestic and foreign application status.According to the heat treatment quality management in Beijing aeronautical manufacturing technology research Institute,the quality management system is not perfect,organizational structure is not sound enough;lack of professional personnel and responsibilities are not clear;afterwards test cost is high;quality information is ineffective and other issues were summary and analysis in this paper.On the basis of research,to build the titanium alloy fastener heat treatment comprehensive quality management system,to organic combination the total quality management theory andproduction of the whole process,to further emphasis on the total quality management core of titanium Alloy Fastener heat treatment is implementation of full participation 、 the whole process of the quality management plan;Established titanium alloy fastener heat treatment of total quality management process;Discusses to carry out total quality management system in the new architecture and continual improvement.By taking out suitable improvement measures,change the quality management from processing results to the process of influence factors,Combination of prevention and control,and giving priority to prevention,for the effective improving of the heat processing quality.Then,evaluated the effect of total quality Management in fastener heat treatment.
