Abstract

Zircon flour is a strong ceramic reinforcement material that is introduced into the melt of zinc aluminium alloy with weight fractions of 1.5, 3.0, 4.5, and 6.0 wt per cent and subjected to the stir casting process. Samples obtained post-stir casting were investigated for morphology using SEM and EDAX, showing the dispersion of zircon flour particles and chemical composition in stir-cast ZA-27 alloy composites. The effect of porosity and hardness of composites on surface properties like wear resistance and coefficient of friction is discussed. Volume loss (cc) in wear was found using density and weight loss in grams at two extreme values of 15N and 60N and a low sliding speed of 0.25 m/s and a high sliding speed of 1.5 m/s using pin on disc experiment as per ASTM standards taking one factor at a time and then optimized using Taguchi L16 array. Wear map and the worn surface revealed oxide debris, abrasion, and wear scratches.

应用田口技术研究锆英粉增强在搅拌铸造锌铝复合材料中的磨损模式

锆石粉是一种坚固的陶瓷增强材料，它被引入到锌铝合金的熔体中，重量分数为1.5%,3.0,4.5和6.0 wt %，并经过搅拌铸造过程。采用SEM和EDAX对搅拌铸造后得到的样品进行了形貌分析，分析了锆粉颗粒在搅拌铸造ZA-27合金复合材料中的分散情况和化学成分。讨论了孔隙率和硬度对复合材料耐磨性和摩擦系数等表面性能的影响。在15N和60N两个极值、低滑动速度为0.25 m/s和高滑动速度为1.5 m/s的情况下，采用针盘式实验，按ASTM标准逐一考虑一个因素，求得磨损体积损失（cc），然后采用田口L16阵列进行优化。磨损图和磨损表面显示出氧化碎屑、磨损和磨损划痕。
