Result show that , after quenching at 980 and tempering at 450 , the rich chromium cast iron exhibits excellent mechanical properties and wear resistance 结果表明，在980淬火， 450回火，高铬铸铁具有优异的力学性能和耐磨性。
High chromium cast iron has higher erosion resistance at lower impact angle , while the erosion resistance is worse for the lower toughness at normal impact 高铬铸铁在低角冲蚀时有较高的耐冲蚀性，但高角冲蚀时由于脆性大，易崩裂。
A study is made on the effects of different heat treatment processes on the structure , mechanical properties and wear resistance of the rich chromium cast iron 摘要本文研究了不同热处理工艺对高铬铸铁组织、力学性能和耐磨性的影响。
28cr high chromium cast iron is one of primary wear resistance materials , which is in use at present . it shows superior performance in corrosion wear and abrasive wear 28cr高铬铸铁是目前使用的主要的抗磨材料之一，在抵抗腐蚀磨损和磨料磨损中表现出优越的性能。
The result showed that , by adopting appropriate casting method , a good metallurgical combination between tungsten particles and hi - cr alloyed cast iron could be obtained 结果表明，在适宜的铸造工艺条件下，碳化钨颗粒和高铬铸铁基体之间可以形成良好的冶金结合，铸渗效果较好。
It is indicated that the dredge pump abrasion resistance parts produced by high - chromium cast iron can meet the demands of design , and its properties may reach the level of products abroad 试制结果证明，使用高铬铸铁生产的泥泵过流耐磨部件符合设计要求，性能达到国外同类产品水平。
The erosive wear behaviors of five engineering materials , include a3 steel , 1crl8ni9ti stainless steel , high chromium cast iron , ptfe and corundum , were studied by an air blast tester under ambient 采用气流喷砂型实验装置测试了a _ 3钢、 1cr18ni9ti不锈钢、高铬铸铁、聚四氟乙烯和刚玉五种工程材料的耐冲蚀性能。
The experimental result of the abrasive wear resistance shows that when the volume percentage of wc particles presented in the layer is about 38 % , the composite layer has the best wear - resistance which is better than the high - cr cast iron 试验结果表明：复合层中保持38 %左右的wc颗粒，其耐磨粒磨损性能最佳，明显高于高铬铸铁，所以这种复合材料具有广阔的应用前景。
