An AlCoCrCuFeNi high-entropy alloy (HEA) coating was fabricated on a pure magnesium substrate using a two-step method, involving plasma spray processing and laser re-melting. After laser re-melting, the microporosity present in the as-sprayed coating was eliminated, and a dense surface layer was obtained. The microstructure of the laser-remelted layer exhibits an epitaxial growth of columnar de...

Organic coating strategies for corrosion protection with inherently conducting polymers have become important because of restriction on the use f heavy metals and chromates in coatings due to their environmental problems. This work presents the synthesis of polyaniline–TiO2 composites PTC) and the corrosion protection behaviour of PTC containing coating on steel. PTC was prepared by chemical ox...

The purpose of this paper is to present a brief overview of the MD* thermal spray process, review the current existing models of heat transfer and fluid mechanics relevant to this process, outline a simplified thermal model implemented together with the results, and discuss the activities required for the implementation and verification of an accurate temperature model of the MD* thermal spray ...

Thermally sprayed 316L stainless steel coatings are commonly used on metallic structures due to their corrosion and wear resistance when compared carbon steel. Cold Gas Spray (CGS) is a convenient thermal spray process deposit coatings, producing thick very dense with almost no deleterious changes the feedstock properties coating condition. The powder characteristics have influence microstructu...

This paper presents three coating methods of photoresist, spin, spray and electrodeposition (ED) on large topography surfaces. Characteristics of each method as well as its advantage and disadvantages are outlined. A comparison is made to point out the most suitable coating method in terms of complexity, costs and type of

Abstract Direct catalyst coating of membranes is an obvious membrane‐electrode assembly (MEA) fabrication approach. Nevertheless, it bears significant challenges related to excessive swelling the wetted and layers during coating. Thermal decaling, which currently used in proton exchange electrolysis, cannot be with typical hydrocarbon‐based anion‐exchange due lack a glass transition point. In t...
