Abstract

ABSTRACT The aim of this study is to improve the tribological behaviour of aluminium alloys by using grain refiner and modifier. The effects of Al5Ti1B grain refiner and Al10Sr modifier additives on friction and wear properties on A380, A357 alloys produced by pouring sand andpermanent mould casting were investigated. Abrasion tests were carried out under dry conditions against St1040 steel disc using a pin-disk system with 20 N load and 1.0 m/s sliding speed. It was determined that grain refiner and modifier additives decrease the friction coefficient and increase the wear resistance. It was determined that the samples produced by permanent mould casting method decreased the friction resistance by 9% and the abrasion resistance increased by 40% compared to the samples produced in sand mould. The lowest wear rate was obtained in A380 alloy with TiB and Sr added with a value of 4.87 × 10–11 m2/N.

晶粒细化剂和变质剂对A357和A380铝合金砂型和永久型铸造磨损性能影响的研究

摘要本研究的目的是通过使用晶粒细化剂和改性剂来改善铝合金的摩擦学性能。研究了Al5Ti1B晶粒细化剂和Al10Sr变质剂对浇注砂和压铸模铸造A380、A357合金摩擦磨损性能的影响。使用销盘系统在干燥条件下对St1040钢盘进行磨损试验，载荷为20N，滑动速度为1.0m/s。结果表明，晶粒细化剂和改性剂的加入降低了摩擦系数，提高了耐磨性。结果表明，采用永久结晶器铸造法生产的试样与砂型试样相比，摩擦阻力降低了9%，耐磨性提高了40%。添加TiB和Sr的A380合金的磨损率最低，其值为4.87×10–11 m2/N。

期刊介绍： The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
