Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Duplex coatings [plasma nitriding followed by physical vapour deposition (PVD) coating] have been given a lot of interest as surface treatment for forming and cutting tools in recent years. The advantage, as compared to conventional PVD coating, is a high

Wear of surface treated dies for aluminium extrusion - a case study
- 2001

Ingår i: WEAR. - : ELSEVIER SCIENCE SA. - 0043-1648. ; 249:3-4, s. 316-323
-
Tidskriftsartikel (refereegranskat)abstract
- Dies for extrusion of aluminium alloys are exposed to severe thermal, chemical and mechanical conditions. Extrusion dies are usually made from hot work tool steels such as AISI H13. In order to reduce wear they are almost always surface treated by various

-
Tidskriftsartikel (refereegranskat)abstract
- The mechanical properties of a series of plasma sprayed ceramic coatings made from alumina, chromia and alumina-titania precursor powders have been evaluated in particle erosion, two-body abrasion and bend testing. For the alumina coatings, both monocryst
