摘要
利用双层辉光离子渗金属技术,在Ti-6Al-4V的表面渗入Cu元素,在其表面形成Ti-Cu阻燃合金层。阻燃合金层的成分及硬度呈梯度分布,显微组织为基体组织加弥散分布的Ti2Cu金属间化合物。初步阻燃试验证明,渗铜合金层起到了预期的阻燃效果。
Cu elements have been introduced into the Ti-6Al-4V substrate by using double glow plasma surface alloying technology to form burn-resistant alloyed layer on the surface. Composition and hardness in the alloyed surface layer gradually change in the depth direction of the substrate and its microstructure is substrate microstructure plus diffused Ti(2)Cu intermetallics.Abecedarian tests reveal that the copperized alloying layer has the function of burn-resistance.
