Iron Powder Metal Gear

The powder metallurgy gear is a kind of metal forming process suit to mass production, different material powder metallurgy gear, its performance is not same. Such as the powder metallurgy gears with copper and stainless steel are not rust, only iron powder metallurgy gear can be rust. So we should how to rust protection for this rust iron powder metallurgy gear?

The first, iron powder storage rust.

Because the purchased iron powder is a powder solid object and there are a lot of holes between iron powder, if the wet gas get into, it will rust in short time and caused can’t use. Thus, the purchased iron powder are package in seal thick plastic bags, and also have desiccant, and use thick woven bag to package the outside for lifting. After mixed iron powder, according to purchased package method and completely sealed, to prevent mixed iron powder oxidizing; place materials to wooden pallet, its use time should control within 2 days.

The second, the using of iron powder in compacting process.

In iron powder metallurgy gear production, we should use the mixed iron powder.Not because of many tasks, so that take out all of iron powder at one time, we must strictly control the iron powder stocks between procedures.
