Description
Technical field
The present invention relates to a kind of compressor that is used for motor vehicle air conditioners, more specifically refer to a kind of swash plate of slant plate type compressor.
Background technique
In the swash-plate-type compressor, wobbler tilts to be installed on the drive main spindle.Swash plate links to each other by crawler shoe with piston in the compressor.Thereby rotation and crawler shoe by swash plate slide, and realize the to-and-fro motion of piston in casing bore, reach air-breathing, the exhaust process of compressor.It is worthy of note: the slide member of compressor inner structure lubricated normally is contained in lubricant oil in the compressor and forms mist of oil with circuit refrigerant gas in the running compressor and take the lubricant oil of mist of oil form to each sliding parts and carry out.Yet, swash plate and crawler shoe begin to slide before lubricant oil arrives its slidingsurface after compressor just starts, and before the slidingsurface between lubricant oil arrival swash plate and the crawler shoe, gaseous refrigerant arrives slidingsurface and washes the lubricant oil that is trapped on the slidingsurface.Therefore, after just starting compressor, swash plate and crawler shoe are not have mutual slip the under the dryness sliding condition of lubricant oil.Turn back to compressor and compressor starts at refrigerant gas and form in time period (about 1 minute) between the mist of oil form, the sliding parts that needs to lubricate under compressor is in lubricating status is in a kind of inadequate lubricating status.The jam phenomenon takes place like this, probably.Even in order to ensure MIN the lubricating of supplying with at oiling agent under the insufficient situation, in order to address this problem, the method for having implemented has by the chemical deposits mode in the method that forms a kind of method of Ni-P coated film and form a kind of Al matter spray-coated film on the irony swash surfaces on the slidingsurface; Be to be presented in slidingsurface in 02127467.3 the patent application to form one and contain solid lubricant (polytetrafluoroethylene) thermoplastic polyimide coating also just like application number.But these technology still can not provide sufficient sliding properties, though or lubricity preferably arranged, but wear resistance is not ideal enough, and the manufacturing process of swash plate is also comparatively complicated, does not have to solve comparatively up hill and dale lubricity and the swash plate wear resistance of compressor in the starting stage.
Summary of the invention
The swash plate that the purpose of this invention is to provide a kind of slant plate type compressor, this swash plate have good lubricated and wear resistance, and manufacturing process is also comparatively simple.
To achieve these goals, the present invention adopts following technological scheme:
A kind of swash plate of this slant plate type compressor, this swash plate comprises matrix and coating, and coating is coated on the matrix, and body material is selected metallic iron/aluminium for use, and wherein: described cladding material is selected the Ni60+20%WC alloy powder for use.
A kind of coating method of coating of swash plate, this painting method may further comprise the steps:
A carries out The pre-heat treatment with the swash plate of making moulding;
B adopts two step of flame mode to spray the Ni60+20%WC alloy powder on through the matrix after the The pre-heat treatment;
C will carry out remelting and handle through the swash plate after the spraying.
In swash plate of the present invention, because cladding material has been selected the Ni60+20%WC alloy powder for use, and after the painting method processing through above-mentioned coating, make to form the comparatively fine and close coating that is metallurgy combination between coating and the matrix, its any surface finish contains W in the coating by analysis
