缸体缸盖渗漏的防止内蒙古工业大学肖柯则缸体和缸盖进行浸水试压时，泄漏率高将严重影响生产厂的经济效益。这种泄漏虽然可用水玻璃或其他有机物进行堵塞通过检验，但铸件质量仍然低下，具体表现在延伸率低，相应铸件抗疲劳、耐磨性能差。造成泄漏的原因是铸件质地疏松，... Leakage prevention cylinder head cylinder Inner Mongolia University of Technology Xiao Ke is the cylinder block and cylinder head pressure test, the high leakage rate will seriously affect the economic benefits of the production plant. Although this leak can be water glass or other organic matter through the blockage test, but the casting quality is still low, specifically in the low elongation, the corresponding castings fatigue resistance, poor wear resistance. Leakage caused by the casting texture is loose, ...
