Herstellung und Eigenschaften neuartiger Beschichtungen mit korrosionsbeständigen Pseudolegierungen auf Fe-Basis durch heißisostatisches Pressen

PM伪合金的一个优点是硬质相颗粒和金属基体粉末的可变组合。为了获得全密度的材料，热等静压是一种适当的工艺，其也可以应用于通过HIP包覆在低合金基底材料上产生涂层。此外，还可以通过热喷涂（例如HVOF）生产厚耐磨涂层。本研究项目的目标是使用不同的工艺路线开发新型PM伪合金。在这种情况下，所考虑的工艺的具体优点应用于某些应用。此外，这些新型合金还针对更高的应用温度进行了设计。性能测量是与TP2和TP4项目合作伙伴密切合作进行的，旨在使合金开发最佳适应磨损和疲劳测试的结果。

One advantage of PM pseudo-alloys is the variable combination of hard phase particles and metal matrix powders. To obtain materials of full density, hot isostatic pressing is an adequate process that can also be applied to produce coatings on low alloyed substrate materials via HIP-cladding. Furthermore, thick wear resistant coatings can also be produced by thermal spraying, for instance HVOF.The ambition of this research project is the development of novel PM pseudo-alloys using different processing routes. In this context, specific advantages of the processes under considerations shall be utilized for certain applications. Besides, these novel alloys are also designed with respect to higher application temperatures. The properties are measured in close collaboration with the project partner of TP2 and TP4 aiming at an optimum adaption of alloy development to results of wear and fatigue testing.
