摘要
A powder metallurgical mixture and a method for the production thereof are described. In addition to powders of base metal and additives, such as graphite, Cu, Ni, Mo, MnS, Fe3P etc and, optionally, a lubricant, the mixture comprises a binder which is at least one diamide wax of the general Formula I: IMAGE (I) wherein R1 and R2 are the same or different and represent a straight, saturated, optionally OH-substituted alkyl group having 13-24 carbon atoms, Q is IMAGE and n is 1-10, the binder being present in molten and subsequently solidified form for binding together the powder particles of the additives with the base metal particles. When producing the mixture, the binder is added to the mixture, and a homogeneous mixture is provided by mixing, the homogeneous mixture is heated to about 90 DEG -160 DEG C. during mixing and melting of the binder, and subsequently the mixture is cooled during mixing, until the binder has solidified.
