The use of conical pick in hard rock cutting processes often leads to severe wear issues due to high-temperature friction. Therefore, enhancing the wear-resistance of the cone of conical pick and studying the thermal distribution and wear patterns during the cutting process are crucial. We employ laser cladding technology to deposit a NiCr-Cr₃C₂ wear-resistant coating on the pick substrate. This study analyzes the influence of process parameters on the properties of coating and investigates the cutting heat and wear conditions. The results indicate that coating hardness is positively correlated with laser power and powder feed rate but negatively correlated with scanning speed. The optimal process parameters are laser power of 2100 W, scanning speed of 10 mm/s, and powder feed rate of 37.5 g/min. During the cutting process, temperature changes can be divided into three stages: rapid heating, slow heating, and thermal equilibrium. The coated picks tend to experience more localized heat concentration at the interface between the coating and substrate compared to uncoated picks. In the cutting process, uncoated picks primarily exhibit adhesive wear, whereas coated picks mainly show abrasive wear. The wear rate of the picks is positively correlated with the heating rate. The wear resistance of spiral coated picks is superior to that of linear ones, reducing wear by 50.3% compared to uncoated picks.
