Fabrication and characterization of W-Cu composite coatings with different W contents by cold spraying

, 2019
W-Cu composite coatings with different tungsten (W) contents were fabricated by cold spraying. The morphology and microstructure were studied using scanning electron microscopy (SEM), with W content and porosity of the final coatings being measured by an

Casting Defects Filling by Low Pressure Cold Spraying Method

, 2014
In this paper the possibilities of using Low Pressure Cold Spraying (LPCS) method for filling the casting defects are presented. In Cold Spraying there is no metallurgical bonding because powder particles are deposited in solid state.

Cold gas spraying of a high-entropy CrFeNiMn equiatomic alloy

, 2020
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

Pores Structure Change Induced by Heat Treatment in Cold-Sprayed Ti6Al4V Coating

, 2019
In this study, the evolution of pores structure in cold-sprayed Ti6Al4V coating (TC4) was analyzed before and after 600-1100 °C heat treatment. It was found that almost no change happened to pores under the heat treatment temperature below 600 °C.
