The present study investigates the influence of mixing ratio copper (Cu) and molybdenum (Mo) powders in Mo-Cu-WC-Si composite powder metallurgy (P/M) briquettes on performance coatings produced Al-2014 alloy using electrical discharge coating. Three ratios Cu Mo are selected during briquette preparation, by varying 5 wt.% decrements increments: 50Cu:30Mo, 45Cu:35Mo, 40Cu:40Mo, with fixed 15WC:5Si. results indicate that even a variation significantly affects coating output responses. At 3 A current 50Cu:30Mo combination shows lowest roughness 2.4 μm, followed 3.2 5.4 μm 45Cu:35Mo 40Cu:40Mo. Coating highest wear reduction, achieving 3-fold decrease compared to uncoated Al-2014. Furthermore, coated samples depict 42% reduction corrosion rate sample. Experimental suggest higher percentage (50 wt.%) provides more suitable

The long‐term cyclic oxidation behavior of a single MoSi 2 coating, 10%, and 50% Ti 3 SiC /MoSi composite coatings on Nb–Si‐based alloys is systematically investigated. thermal gravimetric analysis reveal that the coating initially exhibits stable mass change (–3.7 mg cm −2 ) for ≈37 cycles, followed by rapid increase in gain (2.2 after 100 cycles). demonstrated linear kinetics with 3.5 cycles. Notably, 10% showed superior stability, minimal (–2.7 over scale formed characterized as compact, dense, firmly adhered to substrate, primarily consisting an amorphous SiO matrix interspersed fine TiO grains. After cycles oxidation, both exhibited significant degradation damage at edges.
