摘要

The review explores the potential of laser cladding (LC) as a cutting-edge remanufacturing technique for damaged dozer blade liners (DBLs) and other high-value heavy-duty equipment used in mining operations. Conventional approaches, such as arc welding, have several limitations, including a restricted repairable range and inadequate precision, often resulting in early failures due to defects and high residual stresses induced during remanufacturing. Based on these drawbacks, the review investigates the potential of LC to improve the wear resistance and durability of DBLs in challenging mining conditions such as abrasive kimberlite environments in diamond mines. The review highlights gaps in the literature regarding the wear modes and mechanisms of mining equipment, material and process selection, and the approach to remanufacturing DBLs and other mining equipment using LC. The review approach involves a comprehensive literature review to assess the performance of LC, with a focus on parameter optimisation and material combinations. Critical LC parameters, such as laser power, scanning speed, etc., are reviewed to improve the quality of remanufactured parts. The review findings indicate that LC contributes to environmental and economic sustainability by reducing material waste and improving production efficiency. The review concludes that LC is a viable, cost-effective, and sustainable alternative to traditional methods for remanufacturing high-value mining equipment.
