摘要

用WC、TiC、ZrO2和Al2O3等陶瓷相增强钢进行了抗空化和抗浆料侵蚀的测试。这些复合材料是采用原位（反应渗透，在冶金过程中合成原生碳化物）和非原位（无压力渗透）技术生产的。研究了复合材料的显微组织和硬度。陶瓷相使硬度提高200-350 HV1-10s。冲蚀试验表明，复合材料的耐磨性优于铸钢。相比之下，与铸钢相比，每种复合材料对空化-浆液侵蚀的抵抗能力都较低。

Slurry and cavitation-erosion resistance of steel-ceramic composites manufactured using in-situ and ex-situ techniques

Steels reinforced with ceramic phases such as WC, TiC, ZrO₂, and Al₂O₃ were tested for cavitation- and slurry-erosion resistance. These composite materials were produced using in-situ (reactive infiltration, the syntheses of primary carbides during the metallurgical process) and ex-situ (non-pressure infiltration) techniques. The microstructure and hardness of the composite materials were investigated. The ceramic phases increased the hardness by 200–350 HV1-10s. Erosion tests showed that the manufactured composite materials had higher wear resistance as compared to cast steel. In contrast, each of the composite materials showed lower resistance to cavitation-slurry erosion when compared to the cast steel.
