... (prism and square) were created over the surfaces of both materials by using the 3D-printed technique. Design/methodology/approach The erosion experiments on both materials were performed by using Ducom Erosion Jet Tester. Erosion tests were performed at four different impacting velocities (15, 30...

...Teofil Jesionowski; Andrzej Krysztafkiewicz; Aleksandra Dec In this study, titanium white was investigated, covered with aluminium oxide and silica. The titanium white was produced by Chemical Works Police S.A. under the catalogue symbol of R‐210. Surface of titanium white was modified with silane...

... to be excellent one for coating applications. Surface modification of dolomite ore particles has been carried out using stearic acid in cyclohexane. The modification concerned with the determination of adsorption isotherm, sediment volume, sedimentation rate, and dispersion properties to determine monolayer...

...Charles M. Hansen A procedure described in a new Nordtest method NT POLY 176 has been shown to determine relatively easily whether or not a surface is clean. One simply applies a well‐chosen droplet of liquid and observes whether or not it spreads. If it spreads the surface can be considered clean...
