Integrated cryocooler assembly with improved compressor performance |
摘要 |
A method for forming a mating piston and cylinder sleeve wherein the piston includes an outer diameter and a cylinder sleeve includes a bore for receiving the piston therein and wherein the piston outer diameter and the bore each form bearing surfaces having a gas film maintained in a gap therebetween. The method includes the steps of coating the piston outer diameter with a layer of PTFE based composite material and then diamond turning the piston outer diameter to a final piston diameter. The cylinder wall is also coated with a PTFE based composite layer which may be deposited by an electroless nickel plating process. The cylinder longitudinal bore is then diamond turned to a cylinder final diameter for mating with the piston final diameter.
