耐磨材料堆焊是在一般母材表面熔敷上优质合金,以提高其金属的耐磨损以及耐高温、耐腐蚀、抗冲击的一种焊接技术。随着耐磨材料堆焊技术的快速发展,现已有近百种耐磨材料和数十种耐磨堆焊工艺。如何根据磨损情况及使用要求,选用合适的堆焊材料和堆焊方法,以获得预期的效果,这是值得研究的问题。下面就耐磨材料堆焊的一般原则介绍给大家,以供参考。 1.为了选择合适的堆焊材料和堆焊工艺,首先应根据零件的特点,弄清磨损原因及母材的成份。
Wear-resistant materials Surfacing is the welding of high-quality alloy on the surface of general base metal to improve the wear resistance of the metal and the high temperature resistance, corrosion resistance and impact resistance. With the rapid development of wear-resistant materials surfacing technology, now there are nearly 100 kinds of wear-resistant materials and dozens of wear surfacing process. How to select the suitable surfacing material and surfacing method according to the wear condition and the use requirement to get the expected result is a problem worth studying. The following general principles of wear-resistant materials surfacing introduced to you for reference. 1. In order to select the appropriate surfacing materials and welding process, first of all should be based on the characteristics of the parts, to understand the reasons for wear and the composition of the base metal.
