Effect of Cu on the surface hardness of Ni−B coating for the strengthening of the Cu surface

Abstract

In this paper, the effect of Cu on the decrease of the surface hardness of a Ni-B layer electrolessly coated was investigated. Ni

Effects of critical plasma spray parameter and spray distance on wear resistance of Al2O3–8 wt.%TiO2 coatings plasma-sprayed with nanopowders

“…Plasma-sprayed ceramic coatings have been widely used for structural applications in order to improve resistances to wear, corrosion, oxidization, erosion, and heat [1][2][3][4][5]. Recently, nanostructured materials having excellent properties have received attentions, and thus many efforts have been made to fabricate nanostructured ceramic coatings with nanopowders and to improve surface properties [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. For example, nanostructured Al 2 O 3 -TiO 2 ceramic coatings show much higher wear resistance than conventional Al 2 O 3 -TiO 2 coatings [3,[6][7][8][9][10][11].…”

Coated Polymers -a Review

“…In order to reduce the surface degradation and increase the thermal resistance of the polymer surfaces, the researchers found a viable solution, covering them with ceramic or metal microlayers depending on the intended application and their operating conditions. Thus, ceramic coatings have been widely used for many applications in order to improve resistance to wear, corrosion, oxidation and heat [3][4][5][6]. Metal [7] and cermet powder coatings have been shown to be effective to improve the wear resistance of polymer matrix materials.…”
