Abstract
A linear compressor and a method for manufacturing a linear compressor are provided. A piston of a linear compressor may include a surface treatment body made of aluminum or an aluminum alloy; a first surface treatment provided on an outer surface of the surface treatment body by a first vacuum deposition process; and a second surface treatment provided on an outer surface of the first surface treatment by a second vacuum deposition process.
Claims20
A linear compressor, comprising:
- a piston inserted into a cylinder and reciprocating within the cylinder, wherein the piston includes:
- a surface treatment body made of aluminum or an aluminum alloy;
- a first surface treatment provided on an outer surface of the surface treatment body, by a first vacuum deposition process;
- and
- a second surface treatment provided on an outer surface of the first surface treatment part, by a second vacuum deposition process.
A method for manufacturing a linear compressor, the method comprising:
- forming a piston;
- installing the piston on a jig;
- forming a first surface treatment on an outer surface of the piston using a first plasma generator;
- and
- forming a second surface treatment on an outer surface of the first surface treatment using a second plasma generator.
A linear compressor, comprising:
- a piston inserted into a cylinder and reciprocating within the cylinder, wherein the piston includes:
- a surface treatment body made of aluminum or an aluminum alloy;
- a first surface treatment provided on an outer surface of the surface treatment body, by a first vacuum deposition process;
- and
- a second surface treatment provided on an outer surface of the first surface treatment part, by a second vacuum deposition process, wherein the first surface treatment includes chromium nitride (CrN), and wherein the second surface treatment includes diamond-like carbon (DLC).
