Pulverbearbetning

Pulverbearbetning refers to processes where finely divided solid materials, known as powders, are shaped or joined together. This is a broad category encompassing various techniques used in manufacturing and materials science. One common method is powder metallurgy, where metal powders are compacted into a desired shape and then sintered at high temperatures. Sintering causes the powder particles to bond together, forming a solid, dense object. This process allows for the creation of complex geometries and materials with unique properties that might be difficult or impossible to achieve through traditional casting or machining.

Another aspect of pulverbearbetning involves applying powders as coatings. Thermal spraying, for instance, uses heat to melt or soften powder particles, which are then propelled onto a surface to form a protective or functional layer. This can enhance wear resistance, corrosion protection, or electrical conductivity. Additive manufacturing, also known as 3D printing, frequently utilizes pulverbearbetning techniques. Selective laser sintering (SLS) and selective laser melting (SLM) are examples where a laser selectively fuses powder particles layer by layer to build up a three-dimensional object. The choice of pulverbearbetning method depends heavily on the material properties required, the complexity of the desired shape, and the intended application of the final product.
