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. At the high load, the relative wear resistance of engine cylinder hardened by composite iron plating is twice as high as high phosphors cast iron. By comprehensive contrast of the wear resistance of hardening materials, relative wear resistance of composite iron plating is better than common engine cylinder material, and can fit for the cylinder hardening of high load engine.

Piston Speed

For practical operation conditions of engine cylinder, piston speed and lateral pressure to cylinder wall are determined as experimental factors. According to load and speed on 1mm~8mm below top dead center of cylinder in expansion stroke, the ranges of experimental parameters are chosen. Based on the quadratic regression rotation combination method, wear resistance experiment of hardening material is designed. The wear mathematic models of Ni-P electroless plating is established, and three-dimensional curved surfaces for load-speed-wearing value are drawn. The results show that the Ni-P electroless plating can increase relative wear resistance of cylinder by 5 times. By analysis of wear mechanisms of hardening material and wear resistance, the material is perfect for hardening engine cylinder wall.

Sprayed Coating

Improving the vehicle efficiency by weight reduction and friction loss has become the severe challenge to machinery manufacturers. Generally, replacing heavy cast iron engine component by aluminum alloys played a key role in reducing fuel consumption and pollutants emission, but the durability in poor mechanical properties of aluminum alloys restricted its application in severe conditions of engine cylinder. In order to improve the tribological properties of aluminum cylinder liner, Cr2O3-added Fe-based coating was prepared by plasma spraying technology, and the effect of Cr2O3 on the microstructure and tribological performance of sprayed coating was investigated in this study. All the Cr2O3-added coatings improved mechanical properties significantly, such as hardness and wear resistance compared to that of Fe-based alloy. However, appropriate content of Cr2O3 was beneficial to wear resistant but the excessive Cr2O3 deteriorated the wear resistance under dry sliding condition. The degradation was likely generated by the embrittlement of the Cr2O3 reinforcements, weaker interface of Cr2O3/matrix, and the inherent lamellar structure of sprayed coating. As a result, Fe-based coating with 30 wt.% Cr2O3 provided excellent mechanical properties and can be substitute for the application in aluminum alloy cylinder liner.
