A Review: Thin Protective Coating for Wear Protection in High-Temperature Application

Abstract

Earning trust among high strength material industrialists for its sophistication, thin protective coating has gained its own maturity to date. As a result of active development in the industries, working tool has the capability of fabricating high strength materials with remarkable durability. For example, unwanted tool wear due to thermally softening problems can be avoided. Therefore, the solution for that is protecting the tool with a thin protective coating that can be coated by various coating deposition methods. With the thin protective coating itself possessing remarkable degree of chemical and mechanical properties, the combination of both makes the thin protective coating lead to a useful extend. This paper provides a review of various research activities and various developments in the wear prone industries. Researchers have explored a number of thin protective coatings for the last century to provide a valuable guide for a most practical option. With the state of the art development of the coating methods such as electrodepositing, radio frequency ion source implantation, electron beam implantation, plasma-sprayed coating deposition, flame-sprayed coating deposition, chemical catalytic reduction deposition, vacuum-diffused deposition, vapor deposition, chemical vapor deposition, physical vapor deposition, plasma arc deposition, and some others, this paper presents the continuous development on the enhancement of the capability of the working tool chronologically since the last century. Such development was studied in connection with the ability to outlast the performance of working tool, which elevates expectations that thin protective coatings are no longer extended far beyond.

Defect Types

“…Beyond corrosion-resistant applications where paints are most suitable, over the last few decades, the number of coating of film deposition methods for wear protection in high-temperature applications such as chemical vapour deposition, physical vapour deposition, electrodepositing, radio frequency ion source implantation, electron beam implantation, thermally sprayed coating (air plasma, flame spray, high-velocity oxy-fuel), chemical catalytic reduction deposition, vacuum-diffused deposition and plasma arc deposition has evolved (Awang et al 2020). There are many but some of the materials as a thin protective coating for aircraft applications are polymer, ceramic, diamond-like carbon (DLC), TiN, NiTi, (TiB+TiC)/Ti64, TiAlN, AlCrN, Al 2 O 3 , WS 2 and stellite.…”

Development of a Protective Coating for Evaluating the Sub-surface Microstructure of a Worn Material

“…The co-deposition of hydrogen in the metallic substrate occurs initially as H atoms and not as H 2 molecules. The reduced hydrogen ions can seep in through the broken passive oxide layer, facilitating hydrogen absorption and with time, they may congregate in vacancies or voids leading to hydrogen embrittlement [20]. The hydrogen bubbles evolved at the vicinity of the cathode cling to the freshly electrodeposited surface in an adsorbed state (H ads ), resulting in the development of gas pores in the deposit [39].…”

“…It involves passage of a direct current between the substrate and the metal electrode whilst they are immersed in a solution of the metal. It is one of the few surface-finishing techniques wherein the requirements of both functional and aesthetic applications can be satisfied [20,21]. Moreover, owing to the high degree of controllability obtainable by varying the experimental parameters, it is gaining a lot of attention from the scientific community [22,23].…”

“…Amongst a multitude of potential electrodes, copper (Cu) and nickel (Ni) are widely used owing to their availability and versatility in the deposition process [2,20,22,26]. To prevent inaccurate analysis and erroneous interpretation, electroless Ni coating was employed in coating the oxide layers generated during the wear of a TWIP steel [13].…”

Effect of zircon surface coating on alumina grog and its influences on the properties of low‐cement castables

“…Castables with heat treatment of alumina grog and zircon fines found that better physical and thermal properties, corrosion resistance, HMOR, and RUL. [33][34][35][36] Awang et al 37 fabricated a surface coating layer with different transition metallic materials, inorganic materials, lanthanide materials, and hybrids of these materials. The properties of coating materials include high temperature, high strength, extraordinary thermal fatigue, chemical resistance, low friction coefficient, and affordable cost.…”
