摘要

This study presents a comprehensive evaluation of the abrasion and corrosion resistance of AISI316 vanadium carbide (VC) composite claddings developed on 080M40 steel using the WAAM-CMT technique for enhancing the longevity of agricultural tools. Claddings reinforced with 10% and 20% VC exhibited notable improvements in mechanical and chemical performance. The surface microhardness increased from 233 HV (uncladded substrate) to 362 HV (AISI316), 408 HV (10% VC), and 427 HV (20% VC), marking an overall enhancement of ~ 83%. Dry sand abrasion tests showed a significant 42.8% reduction in mass loss for the ASV20 cladding compared to the base material, attributed to the formation of a hard, wear-resistant load-bearing structure by VC particles. Corrosion resistance, assessed via salt spray testing, improved markedly, with ASV20 achieving a corrosion rate of 0.00028 mm/year approximately 86% lower than the substrate’s 0.00204 mm/year. SEM analysis confirmed uniform VC dispersion in the AISI316 matrix, which acted as effective barriers against abrasive wear and chloride ion ingress. These findings highlight the superior performance of VC-reinforced AISI316 claddings for soil-engaging components under harsh environmental conditions.
