Impact of Zirconium Oxide and Tantalum Carbide Powder Coatings by Plasma Spraying Techniques on Engine Performance
The emission released by diesel engines NOx, CO, CO2, and HC leads to human discomfort and environmental changes. Coating on the piston is an efficient method and innovative approach to decrease emissions in diesel engines. In this work, coating is carried out on the piston crown in a single-cylinder diesel engine and is compared with the uncoated piston. The percentage composition was coated on the piston crown namely, 95% ZrO2 + 5% TaC, 97% ZrO2 + 3% TaC, 98% ZrO2 + 2% TaC, and 100% ZrO2 using plasma spray coating. The brake thermal efficiency of the piston coated with a mixture of 95% ZrO2 and 5% TaC is 8.1% more than that of the uncoated piston. Similarly, the mechanical efficiency of the coated piston is 11.6% greater than that of the unprotected piston.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
