| 中文摘要: |
| 目的 检测六种常用金属饰品材料的耐磨蚀性能，对比分析饰品材料保持光亮度的能力。方法 选择H70黄铜、316L不锈钢、TA2纯钛、CoCrMo合金、钨钢（WC）、TaC系硬质合金六种有代表性的饰品用金属材料，检测其化学成分、硬度及在人工汗液中的极化行为，采用人工汗液+漩涡研磨的方法检测各材质戒指试样的磨蚀失重率，采用扫描电镜观察试样磨蚀形貌。结果 试验材料在人工汗液中点蚀电位由高到低的顺序为TA2>CoCrMo>TaC系硬质合金>316L>钨钢（WC）>H70，初始硬度的高低顺序为H70TA2>316L>CoCrMo>TaC系硬质合金>钨钢（WC）。结论 在人工汗液+漩涡研磨条件下，试样受到腐蚀与机械磨损的交互作用而失重和失去光亮度。除H70外，其余材质受到的腐蚀作用均相对较弱，机械磨损作用较强。材料表面硬度越高，抗磨损性越强，越有利于保持饰品表面的光亮度。 |

| The work aims to test the abrasion resistance of six common metallic materials for ornaments, and contrastively analyze the ornament material’s ability of maintaining surface glossiness. Six typical metallic materials for ornaments, i.e. H70 brass, 316L stainless steel, TA2 pure titanium, CoCrMo alloy, tungsten carbide and TaC system carbide were selected, their chemical composition, hardness and polarization behavior in artificial sweat were detected, abrasion weight loss rate of various ring samples was tested in the method of disc polishing in the artificial sweat, and abrasion morphology was observed by using SEM. Pitting potential of the test materials in artificial sweat sorted from high to low was as follows: TA2>CoCrMo>TaCsystem carbide>316L>tungsten carbide>H70, and initial hardness: H70TA2>316L>CoCrMo>TaC system carbide>tungsten carbide. Provided with the working condition of disc polishing+artificial sweat, the samples will experience weight loss and glossiness reduction under the interaction effect of mechanical wear and corrosion. However, corrosive action on the other samples other than H70 is relatively weaker, while me-chanical wear action is stronger. Thus, the higher the material’s surface hardness is, the better the abrasion resistance is, and the more conductive to maintain surface glossiness of ornament surface will be. |
