Nickel-chrome coatings are widely used to improve surface properties and service life of engineering components made from different ferrous and non-ferrous alloys. Herein, an attempt has been made to investigate the impact of various voltages ranging from 26-30 V and spray-off distances ranging from 100-300 mm of electric-arc spray technique on the surface properties of Ni-Cr coating developed on 304L stainless steel. Thickness, porosity, surface morphology, surface roughness, and hardness of Ni-Cr coatings were determined to study the impact of deposition parameters. Coating deposition at 26 V exhibited the lowest porosity and the highest percentage of Cr nodules among all samples. The comparison study showed that coating deposit developed at 26 V and 100 mm spray-off distance has a maximum thickness, followed by coating developed at 30 V and 100 mm spray-off distance. This indicated that coating deposit developed at 100 mm spray-off distance results in thicker coatings. Maximum hardness was achieved at 30 V and 300 mm spray-off distance. The shorter spray-off distance revealed that coatings tend to be thicker and harder resulting in longer coating life.

“…Typically, the intrinsic defects of plasma-sprayed coatings, such as pores (porosity), un-molten or partially melted particles and cracks have adverse effects on the mechanical, physical and chemical properties of the coatings. The porosity is one of the typical features of plasma-sprayed coating, can deteriorate the protective performances of the coatings in harsh working environments [3]. In this work, porosity development in plasma-sprayed coatings and the impacts of varying set spraying parameters on porosity were studied.…”

Porosity and Its Significance in Plasma-Sprayed Coatings

Porosity in plasma-sprayed coatings is vital for most engineering applications. Porosity has its merits and demerits depending on the functionality of the coating and the immediate working environment. Consequently, the formation mechanisms and development of porosity have been extensively explored to find out modes of controlling porosity in plasma-sprayed coatings. In this work, a comprehensive review of porosity on plasma-sprayed coatings is established. The formation and development of porosity on plasma-sprayed coatings are governed by set spraying parameters. Optimized set spraying parameters have been used to achieve the most favorable coatings with minimum defects. Even with the optimized set spraying parameters, defects like porosity still occur. Here, we discuss other ways that can be used to control porosity in plasma-sprayed coating with emphasis to atmospheric plasma-sprayed chromium oxide coatings. Techniques like multilayer coatings, nanostructured coatings, doping with rare earth elements, laser surface re-melting and a combination of the above methods have been suggested in adjusting porosity. The influences of porosity on microstructure, properties of plasma-sprayed coatings and the measurement methods of porosity have also been reviewed.

Porosity in plasma sprayed coatings is vital for most engineering applications. It is either advantageous or disadvantageous depending on the functionality of the coating and the immediate working environment. Consequently, the formation mechanisms and development of porosity has been extensively explored to find out modes of controlling porosity in plasma sprayed coatings. In this work, a comprehensive review of porosity on plasma sprayed coatings is established. The formation and development of porosity on plasma sprayed coatings are governed by set spraying parameters. Optimized set spraying parameters have been used to achieve the most favorable coatings with minimum defects. Even with the optimized set spraying parameters, defects like porosity still occur. Here, we discuss other ways that can be used to control porosity in plasma sprayed coating with emphasis to atmospheric plasma sprayed chromium oxide coatings. Techniques like multi-layer coatings, nano-structured coatings, doping with rare earth elements, laser surface re-melting and a combination of the above methods have been suggested in adjusting porosity. The influences of porosity on properties of plasma sprayed coatings and the measurement methods of porosity have also been reviewed.
