The corrosion behavior of copper cold spray coatings on a carbon steel substrate was compared to that of commercially available wrought copper under the conditions anticipated in a nuclear waste repository. Corrosion potential and linear polarization resistance measurements were conducted over 90 d to 120 d in 3.0 mol/L NaCl under anoxic (1) and oxygenated-toanoxic (2) conditions to simulate th...

The concept of dry surface treatment for paper coating applications has been available for more than ten years. Different from conventional coating methods such as extrusion coating and suspension coating, dry surface treatment involves a combined process of non-contact deposition of coating materials and surface smoothening of the coated paper. Pronounced features of this concept include avoid...

The industrial robot plays a very important role in stabilizing and improving the quality of products, production efficiency, working conditions and the rapid upgrading of products. It is often composed of a mechanical body, control device, driving system and detection and sensing device, and can be used in three-dimensional space to complete integration of automatic production and processing e...

This work describes a novel technique for the deposition of surface-attached hydrogels, which is based on combination spray coating and CH-insertion cross-linking (CHic) to create protein repellent surface. To this, hydrogel precursor polymers are coated onto surface be modified, dried, photo cross-linked in solid state. Spray allows application precursors fast flexible way, so that even geomet...

In this study, the effect of surface roughness and roughness morphology on the bond strength of WC-Co-Cr coatings has investigated. The three different surfaces morphology are use for this purpose. The first and tow samples sandblasted with alumina and silicon carbide respectively. Other sample no sandblasted before spraying process. The same WC-10Co-4Cr coating deposited on the substrates with...
