Plastic supplies nice design freedom, allowing for gear configurations too troublesome or costly to create in metal, similar to cluster gears, during which a couple of gear is created in a single molded half. Plastic gears also offer good loading properties, relatively low noise, excellent wearability and lu bricity, and good chemical and thermal resistance. In this report, an aluminium metallic matrix was bolstered additional info with 1.5 wt. Microstructural examination performed on the sample revealed a uniform distribution of alumina particulates. It was found that sliding put on resistance improved considerably with the addition of alumina nano particles. \It’s …
