The failure of plasma-sprayed thermal barrier coatings (TBCs) during service is usually related to the cracking behavior. In this study, TBCs were prepared with two kinds agglomerated sintered yttria-stabilized zirconia (YSZ) powders different particle sizes. evolution mechanical properties and crack propagation behavior whole life stage studied by a shock test. effect powder size on was analyz...

Castings of aluminum and plastics are of high importance in the industrial world. They are usually made using permanent metallic moulds for pressure die-castings and injection molding. Die-tools are usually produced from chromium maraging hot work tool steel and are heat treated to hardness between 29 and 48 HRC, 1-3 . Die life is a mayor factor of a die-casting process and it strongly affects ...
