Material for manufacturing aluminum piston abrasion-proof inserted ring

Abstract

Material for wear-resisting ring of piston contains (mass%) C 2.7-3.3, Si 2.7-3.6, Mn 6.0-9.0, Ni 5.0-13.5, Cu 3.0-6.0, and balanced with Fe, with impurities of Cr 1.0 and S 0.1 and P 0.5 less than the values said above. The material reduces content of Ni so as to cost low.

Description

technical field [0001] The invention relates to a new material for manufacturing an aluminum piston wear-resistant insert ring, which belongs to the technical field of internal combustion engine materials. Background technique [0002] The material for making wear-resistant inserts for aluminum pistons requires thermal expansion properties similar to those of aluminum piston materials, good wear resistance, and good mechanical and physical properties. In order to meet this requirement, the composition contains more nickel, which is higher than 13.5 %, and the high price of nickel leads to higher cost of materials, which affects its application. Contents of the invention [0003] The purpose of the present invention is to provide a new material for manufacturing aluminum piston wear-resistant inserts, which has low nickel content, low material cost and good application performance. [0004] The material for manufacturing the wear-resistant insert ring of the aluminum pisto...
