Powder Manufacturing Methods.
There are four basic methods of producing powders for thermal spraying. These are "crushing
", "agglomeration", "chemical" and "atomisation". Each method can be further sub-divided and powders can also be made by
various combinations from each group. As a result there is a wide range of production routes available each producing
powders with their own particular characteristics. Published on SurfaceWeb on 24/06/98.
