Ensuring adequate reliability of the production process of packaging closures has made it necessary to study the effect of annealing and varnishing variants on the strength and structural properties of the stock material. As a test material, EN AW-5052-H28 aluminium alloy sheets with a thickness of 0.21 mm were used. The surface treatment of the test material involved varnishing the sheet metal surface using various varnishes and soaking the sheet metal. The coefficient of friction and the abrasion resistance of the coatings were determined using the T-21 ball-and-disc tribotester. The tested sheets were subjected to tribological analysis by the T-05 roller-block tribotester using countersamples made of Caldie and Sverker 21 tool steels. The results of the tests showed differences in mechanical and structural properties depending on the method of sample preparation. Based on the test results, significant differences in the adhesion of anti-wear coatings were found. The results revealed that the most favourable friction conditions are provided by the CrN coating. The (AlTi)N interlayer in the (AlTi)N/(AlCr)N coating adheres to the substrate over the entire tested area and no detachment from its surface was observed, which proves good bonding at the substrate/coating interface. The tested AlTiN/TiAlSiXN coating is characterised by a more homogeneous, compact microstructure compared to the (AlTi)N/(AlCr)N coating.
确保包装封盖生产过程具有足够的可靠性,因此有必要研究退火和涂漆工艺对原材料强度和结构性能的影响。作为测试材料,使用了厚度为0.21毫米的EN AW-5052-H28铝合金板材。测试材料的表面处理包括使用各种清漆对金属板材表面进行涂漆以及对板材进行浸泡处理。使用T-21球盘摩擦磨损试验机测定涂层的摩擦系数和耐磨性。使用由卡尔迪(Caldie)和斯韦尔克21(Sverker 21)工具钢制成的配对试样,通过T-05滚子-滑块摩擦磨损试验机对测试板材进行摩擦学分析。测试结果表明,根据样品制备方法的不同,机械性能和结构性能存在差异。基于测试结果,发现抗磨涂层的附着力存在显著差异。结果表明,CrN涂层提供了最有利的摩擦条件。(AlTi)N/(AlCr)N涂层中的(AlTi)N中间层在整个测试区域内都与基底紧密结合,未观察到从其表面脱落的现象,这证明了在基底/涂层界面处具有良好的结合力。与(AlTi)N/(AlCr)N涂层相比,测试的AlTiN/TiAlSiXN涂层具有更均匀、致密的微观结构。
