Use of metallic powders has converted from isolated and very special applications in the 30is of the past century into a commonly applied resource to be used in a wide range of industrial applications of today’s. Metallic powders can be distinguished and classified by:
- Method of production
- Chemical composition
- Type of particle formation
Depending on production method, powders are produced by grinding (crushing), atomization, chemical or electrical precipitation as well as by a lot of special processes.
Such production methods give the powders special characteristics which qualify the powders for various applications. Welding consumables and base materials for versatile sintering techniques are the most comprehensive applications, from quantity as well as from level of demanding characteristics.
Atomization is the most versatile process, when defined chemical compositions are required for the application. Almost any chemical composition can be realized with a molten alloy which will be atomized by several methods. So it is guaranteed that any particle is of identical chemical composition. With this base, shape and size of particles can be tailored to its applications: production of sintered components (conventional press sintering, metallic filter production, metal injection moulding, plasma surfacing, laser bed sintering for 3-D printing etc.). There is an uncountable number of different applications in today’s industry from smart phone (soft magnetic powders) to turbine vane production (high temperature resisting powders).
