Abstract (en)
The scroll compressor includes a casing comprising a rotation shaft; a discharge cover fixed inside the casing to partition the inside of the casing into a suction space and a discharge space; a back pressure plate defining a back pressure chamber for accommodating a refrigerant, a floating plate to define the back pressure chamber together with the back pressure plate, the floating plate including a contact part that is capable of contacting the discharge cover, and a coating layer defining an outer surface of the contact part. The discharge cover has a first hardness value, the floating plate has a second hardness value, and the coating layer has a third hardness value, and the third hardness value is less than the first hardness value and greater than the second hardness value.
