The article compares the properties of coatings (cataphoretic, hot-dip zinc, and thermo-diffusion zinc) applied to steel components used in the automotive industry. The research focused on the analysis of corrosion resistance, hardness measurements, and tribological properties conducted on steel guides used in trailer and truck body structures as well as fasteners (M12 × 40 bolts). The base surfaces were cleaned chemically. Corrosion resistance was tested in a salt chamber, while coating thickness was measured using the magnetic induction method. Coating hardness (HV 0.02) was assessed with a microhardness tester, and tribological properties were tested under dry friction conditions. The results showed that the zinc coatings demonstrated corrosion resistance far superior to paint coatings.
本文比较了应用于汽车工业用钢部件的涂层（电泳涂层、热镀锌涂层和热扩散镀锌涂层）的性能。该研究聚焦于对用于拖车和卡车车身结构的钢导轨以及紧固件（M12×40螺栓）进行耐腐蚀性分析、硬度测量和摩擦学性能测试。对基体表面进行了化学清洗。在盐雾试验箱中测试耐腐蚀性，同时使用磁感应法测量涂层厚度。用显微硬度计评估涂层硬度（HV 0.02），并在干摩擦条件下测试摩擦学性能。结果表明，锌涂层的耐腐蚀性远优于油漆涂层。
