Oct 01, 1996 · Electrical insulation of the structural material is necessary to reduce the MHD pressure drop in a self-cooled liquid metal blanket. This coating has to be compatible with liquid Pb sbnd 17Li up to 450°C. Specimens with different types of coatings were exposed to static Pb sbnd 17Li for 1200 h at 450°C in order to study their compatibility. Iron and a ferritic steel were coated with an
Coatings Free Full-Text Cold Gas Spraying of a High Cold gas spraying was used to make a coating from an equiatomic CrFeNiMn high-entropy alloy. This four-component alloy was chosen because it is Co-free, thus allowing application in nuclear industries as a possible replacement of currently used stainless steel coatings. The feedstock material was gas atomized powder with a particle size distribution from 20 to 45 µm.

Mechanical Performance of Cold-Sprayed A357 Aluminum Sep 25, 2017 · Abstract. Cold-sprayed coatings made of A357 aluminum alloy, a casting alloy widely used in aerospace, underwent set of standard tests as well as newly developed fatigue test to gain an information about potential of cold spray for repair and additive manufacturing of loaded parts. With optimal spray parameters, coating deposition on substrate with smooth surface resulted in relatively
Modelling of alloying process of cold sprayed Ni/Al coatingAug 01, 2019 · The diffusion in the alloying process of the cold sprayed coating is not only affected by diffusion-induced stress, but also by residual stress resulting from cold spray process, thus the effect of residual stress must be considered. The abovementioned diffusion models cannot reasonably describe the alloying process.
Sep 25, 2010 · A coating is highly functional only if the interface between the coating and the substrate is reliable and strong. The bonding of particles in cold spray is presumed to be the result of extensive plastic deformation and related phenomena at the interface, such as spray jet formation and spray splats interlocking . The bonding mechanisms in cold spray can thus be compared to those in explosive Influence of coatings and alloying on cold welding due to Sep 01, 2003 · Influence of coatings and alloying on cold welding due to impact and fretting Merstallinger, A.; In the following, a standardised test method was set-up, in order to compare different space relevant materials and coatings for their tendency to cold welding. Within several studies, common experience and numerical results were gained on space
