热喷涂工艺制备铝基非晶态合金材料研究进展

传统的铝基非晶态合金的制备方法有急冷法和机械合金化法.急冷法使用方便,冷却速率快,可获得非晶,可实现连续生产；机械合金化法具有设备简单,操作方便,易工业化,合金成分范围相对较宽等优点.但是这两种方法只限于制备非晶条带、薄片或粉末,而且生产制备周期较长,生产效率较低.热喷涂技术作为一种新兴的制备工艺,可获得非晶涂层,实现...

Research Progress of Al-based Amorphous Alloy Materials Prepared by Thermal Spraying Process

The conventional preparation method of Al-based amorphous alloy consists of the rapid solidification and mechanical alloying technique.The rapid solidification with convenience and rapid cooling rate can produce an amorphous phase and achieve successive production.The mechanical alloying has simple equipments,convenient operation,easy industrialization,relatively wide range of alloy composition,and other advantages.But both methods can only prepare amorphous ribbons,flakes or powders,and the production period is long and the production efficiency is low.Thermal spraying technique is a kind of rising preparation technique,which can produce amorphous coating,and achieve integration of materials preparation and forming to reduce the production period.So it has been the key preparation technique of industrialized application.
