具有高耐磨性的材料是许多工具应用的兴趣。出于经济原因，需要几毫米厚的涂层。这些材料在低合金基板上的包层通常使用热等静压，这是一个成本密集的过程，特别是对于长产品。因此，最近开发了一种新的生产路线，即直接热挤压封装的块状钢筋和预压的工具钢粉末。通过这种方法，可以加工PM工具钢的耐磨包层和钢基体上的耐磨MMC。
Materials with high resistance against abrasive wear are of interest for many tool applications. For economical reasons, thick coatings of several millimetres are requested. The cladding of these materials to low alloyed substrates is commonly performed using hot isostatic pressing, being a cost intensive process in particular for long products. Thus, a novel manufacturing route via direct hot extrusion of encapsulated bulk steel bars and presintered tool steel powders was recently developed. In this manner, wear resistant claddings of PM tool steels and wear resistant MMC on steel substrates could be processed.
