Abstract

本发明公开了一种涂层钨材，包括钨基材，在所述的钨基材上涂覆有厚度为3－30μm的TiN或Cu(余量)－(15－45)％Zn－(0.1－1.5)％Ni－(0.5－1)％Al2O3合金涂覆层。所述钨基材的组成为纯钨或W(余量)－2％Ni－1％Fe合金；所述钨基材的相对密度为纯钨理论密度的97－99.9％。本发明的涂层钨材，在保证钨基材料高的相对密度条件下，有效提高钨基材料表面的抗氧化性、耐磨性、耐汗渍腐蚀性和色彩鲜艳性等综合使用性能，使高密度钨基材料得到更广泛的应用。本发明产品制备简单，成本低廉，适合于常规生产工艺。

Description

涂层钨材
技术领域
本发明涉及一种钨材，特别是涉及一种涂覆有涂层的高密度钨基材。
背景技术
高密度钨基材料被广泛用于国防军工、机械电子、航天航空、冶金矿山、石油煤炭、钟表饰品等领域。未涂层的钨材存在不耐磨、抗氧化性差、易汗渍腐蚀，以及色彩暗淡等缺陷。
发明内容
本发明所要解决的技术问题是提供一种抗氧化性、耐磨性、耐汗渍腐蚀性和色彩鲜艳性等综合使用性能较高的涂层钨材。
为了解决上述技术问题，本发明提供的涂层钨材，包括钨基材，钨基材的组成为纯钨或W(余量)-2％Ni-1％Fe合金，在所述的钨基材上涂覆有厚度为3-30μm的TiN或Cu(余量)-(15-45)％Zn-(0.1-1.5)％Ni-(0.5-1)％Al2O3合金涂覆层。
采用上述技术方案的涂层钨材，由于在钨基材上涂覆有TiN或铜合金涂层，可以在保证钨基材料高的相对密度条件下，有效提高钨基材料表面的抗氧化性、耐磨性、耐汗渍腐蚀性和色彩鲜艳性等综合使用性能，使高密度钨基材料得到更广泛的应用。本发明产品制备简单，成本低廉，适合于常规生产工艺。
