Description

technical field [0001] The invention relates to the technical field of coatings on the inner walls of automobile cylinders, in particular to an environmentally friendly and wear-resistant coating on the inner walls of high-strength internal combustion engine cylinders and a preparation method thereof. Background technique [0002] Energy saving and emission reduction has become the ultimate goal of global auto companies. According to data, in the emission of air pollutants, CO accounts for 66%, NOx accounts for 43%, HC accounts for 31%, CO 2 33% of air pollution and 20% of particulate matter come from vehicle emissions. The lightweight of automobiles is very important to save energy and reduce exhaust emissions. The use of aluminum alloy internal combustion engines to gradually replace traditional cast iron internal combustion engines is one of the main ways to save energy and reduce emissions. However, because the strength and stiffness of aluminum alloy are lower than t...
