WEAR RESISTANCE ANALYSIS OF HARDENING MATERIALS FOR ENGINE CYLINDER
In order to improve wear resistance of engine cylinder, the surface hardening technology is analyzed. The hardening methods which iron plating and composite iron plating have application in engine cylinder repair are put forward. The relative speed and pressure between piston ring and cylinder wall are determined as main wear factors of engine cylinder. And wear resistance of hardening material is chosen as assessment index. To consider the parameters of engine operating condition, the wear test bed with high speed and stepless speed regulation is designed. The contrast experiments are processed in simulation engine running condition. The relative wear resistance of engine cylinder hardened by composite iron plating is increased by two times. The results show that the wear resistance of engine is improved obviously and service life can be extended.
