    Influence of SiC Concentration in Slurry on Microscale Abrasive Wear of TZNT Titanium Alloys

      摘要
    • 摘要: 用TE66型试验机分析了TZNT钛合金的微粒磨粒磨损行为,用15JE型数显式测量显微镜测量了磨斑直径,研究了料浆中碳化硅含量(0.05~0.25 g·cm-3)对合金磨损体积的影响,并建立了磨损机制图.结果表明:在0.05~0.50 N载荷下,TZNT钛合金的磨损体积均随着料浆中碳化硅含量的增加而增大;且在相同条件下,其在Hanks模拟体液中的磨损体积小于其在蒸馏水中的磨损体积;随着料浆中碳化硅含量的增加,TZNT钛合金的磨损形式由二体磨损向混合磨损和三体磨损转变.

       

      Abstract: Microscale abrasive wear of TZNT titanium alloys was analyzed using a TE66 abrasion tester.The wear scar diameter was measured using a 15JE microscope.The influence of SiC concentration in slurry (0.05-025 g·cm-3) on wear volume was investigated.Microabrasion mechanism maps for TZNT titanium alloys were also constructed.The results showed that the wear volume increased with the increase of SiC concentration in slurry.Under the same conditions,the wear volume of TZNT titanium alloys in Hanks solution was less than that in distilled water.With the increase of SiC concentration,microabrasion mechanism of TZNT titanium alloys transformed from two-body abrasion to mixed abrasion and three-body abrasion.
