Abstract
The invention discloses a local carburizing method of an auto air-condition compressor eccentric gear. The local carburizing method of the auto air-condition compressor eccentric gear comprises the ultrasonic cleaning, oven dry, coating and carburization to the auto air-condition compressor eccentric gear. The local carburizing method of the auto air-condition compressor eccentric gear is characterized in that the coating is that 5%-10% of nanoscale polytetrafluoroethene by weight is added into polyamide acid. After the polyamide acid is stirred evenly, the polyamide acid is coated parts of the eccentric gear, wherein the parts of the eccentric gear do not need to be carburized. The thickness of the coating can be 0.05 millimeters to 0.5 millimeters. After the coating is dried and solidified, the eccentric gear is placed inside a vacuum carburization furnace to achieve the low pressure carburizing process. According to the local carburizing method of the auto air-condition compressor eccentric gear, due to the fact of the heat stability of the coating is high and the coating and the eccentric gear mental surface are good in binding force, the coating cannot be peeled to the mental materials of the eccentric gear without any side effects. The coating is further provided with the protective function of anti-corrosion on the surface. The environment is not only polluted, but also prevented the carbon from seeking. The quality of the local carburization of the auto air-condition compressor eccentric gear is ensured.
Description
Technical field
The present invention relates to the eccentric local carburization method of a kind of automobile air conditioner compressor production technology, particularly a kind of automobile air conditioner compressor.
Background technology
In metallic surface carburizing treatment process, mostly adopt at present and in vacuum oven, realize low-pressure carburization, its temperature range is 930 ~ 980 ℃, top temperature can reach 1040 ℃, in order to realize local carburization, for the part that requires local carburization, carry out antiseepage, common anti-seepage method has following several: 1, pre-made allowance excision method: namely do not answer the position of carburizing at part, reserve in advance the process redundancy slightly thicker than cementation zone, with mechanical means this part is excised after the carburizing again.This method is reliable, but the loss in material and man-hour is larger, and complex-shaped part wants excision remainder punching also difficult.And can not carry out direct quenching; 2, Coating Method: add that with 1/3 red lead and 2/3 cupric chloride the rosin that accounts for bi-material total amount 10-15% mixes, be dissolved in and become pasty state in the organic solvent (alcohol, gasoline), being applied to writing brush does not need the carburizing position, and the about 0.7-1.0mm of thickness is coated with one deck again after the drying.But present this coating is unable to undergo hot environment, infiltrates so still can produce carbon; 3, copper-plating method: plate the copper layer that thickness is 0.02-0.04mm at the position that does not need carburizing with electro-plating method, the infiltration of anti-blocking that can be reliable, but electroplate the pollution that brings again environment.
Summary of the invention
The objective of the invention is provides a kind of both free from environmental pollution in order to solve above-mentioned the deficiencies in the prior art, can prevent again the infiltration of blocking, guarantees the eccentric local carburization method of automobile air conditioner compressor of local carburization quality.
To achieve these goals, the eccentric local carburization method of a kind of automobile air conditioner compressor provided by the present invention, comprise the eccentric ultrasonic cleaning of automobile air conditioner compressor, oven dry, coating and carburizing, it is characterized in that described coating is that nano level polytetrafluoroethylpowder powder 5%-10% is by weight joined in the polyamic acid, be applied to eccentric wheel after stirring and do not need the carburizing position, coat-thickness can be 0.05 millimeter to 0.5 millimeter, after coated and dried is solidified eccentric wheel is put into vacuum cementation furnace and realizes the low-pressure carburization processing.The mixture of described nano-powder adopts diameter of particle to reach the nanometer grade powder of D＜1um.Described nano level polytetrafluoroethylpowder powder can adopt the polytetrafluoroethylpowder powder of Du Pont's series, such as the Zongyl Mp of Du Pont; The Zongyl of Du Pont 1200; Or the Zongyl of Du Pont 1500.
The eccentric local carburization method of automobile air conditioner compressor provided by the invention, because there is good bonding force the thermostability of coating height, coating and eccentric wheel metallic surface, coating can not peeled off, to eccentric metallic substance without any side effect, also has the surface corrosion resistance provide protection, in cementation process, guaranteed in cementation process, do not need the part of carburizing not to be subjected to the impact of carburization process; Carburizing of the present invention rapidly, processing ease, equipment be simple, convenient, and quality product is high, and power consumption consumption gas is economized, and is both free from environmental pollution, can prevent again the infiltration of blocking, guarantees the eccentric local carburization quality of automobile air conditioner compressor.
