The microstructure was characterized with low porosity and fine grain structure. In addition, after post-processing heat treatment, the microstructure became denser (i.e. lower porosity). The microhardness did not change with 400°C annealing temperature but decreased significantly at 800°C, which can be explained by the recrystallization that occurs during cold-spraying. Both the ductility and strength were improved after annealing at 1100°C, in particular. 2- This study shows the ability to successfully cold-spray composite 316L-CoCr using nitrogen as a propellant gas with Co-Cr volume fractions (i.e. 25%, 33.3%). The deposition efficiency decreased with increasing the amount of Co-Cr. The microstructure is characterized by low porosity level in the first two mixes. At 50% as mixed Co-Cr and 316L, the actual as coated material was 33% Co-Cr, due to difficulties in bonding Co-Cr particles to each other. Thus, the porosity was high at the 50% mixture and cracks were also apparent.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783848421572\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783848421572","offer_id":39457347600477,"sku":"9783848421572","price":54.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/36eac1cf-8eb3-491d-85eb-b8297bf7fb3e.jpg?v=1769495283","url":"https:\/\/shop.autorenwelt.de\/products\/the-use-of-cold-sprayed-alloys-for-metallic-stents-von-bandar-almangour","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
