7. 5. Surface Interactions in Powder Injection Moulding

   Författare :Elisabeth Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; powder injection moulding PIM ; rheology; steel powder; surface interactions; XPS; SIMS; adsorption; surface composition;

   Sammanfattning : Powder Injection Moulding (PIM) is an attractive technique for producing complex components in large quantities my means of powder technology. The process includes mixing powder with a suitable binder, usually a thermoplastic polymer. Because of the large attractive forces between small particles the powder can be agglomerated in the binder. LÄS MER
