RESIN COATING LAYER HAVING HIGH ABRASION RESISTANCE FOR A PISTON SKIRT UNIT AND A MANUFACTURING METHOD THEREOF, FOR IMPROVING THE DURABILITY WHEN COMPARING WITH THE EXISTING PRODUCT

摘要

PURPOSE: A resin coating layer having high abrasion resistance for a piston skirt unit and a manufacturing method thereof are provided to lower the abrasion speed by supporting a resin coating layer having high abrasion resistance with the filled abrasion resistant particle block.;CONSTITUTION: A resin coating layer having high abrasion resistance for a piston skirt unit comprises a peak part(12a), a valley part(12b), a housing groove, and an abrasion resistant particle block. The peak part is coated on the basic material surface of a skirt part(11) of a piston(10) and is projected to the friction side with the inner wall of a cylinder. The valley part is concavely formed between the peak parts to the direction opposite to the friction side with the inner wall of the cylinder. The housing groove is formed in the valley part by etching. Abrasion resistant particles are filled in the housing groove in the abrasion resistant particle block.;COPYRIGHT KIPO 2010
