天纳克研发新型耐磨材料:减轻发动机应用对钴材料的依赖

Tenneco Develops New Wear-resistant Material to Reduce the Dependence of Engines on Cobalt Materials

美国天纳克公司动力总成业务部研发出一种创新材料,具备高耐磨性,可大大降低钴含量,帮助发动机制造商缓解钴量有限、钴价波动大等问题。重型涡轮增压器废气门衬套、废气再循环阀和高性能发动机的气门座圈等高要求的高温产品都需要依赖钴,以使其能够在高温工作范围内具备高耐磨性。因此,此类产品将受益于这种新材料的应用。试验表明,利用新的烧结钢配方,天纳克烧结材料中的钴含量可大大降低,而且不会影响产品性能。

The Powertrain Business Department of Tenneco has developed an innovative material with high wear resistance,which can greatly reduce the cobalt content,and help engine manufacturers alleviate the problems such as limited cobalt reserve and great fluctuations in cobalt price.
