激光包覆技术可利用火焰喷涂、等离子喷涂、爆炸喷涂层或直接利用粉末或线、箔态材料在受控条件下用激光束予以熔化,让溶化材料散布与凝固,形成包层与基体之间的金相结合。包复材料可以是钴基合金、钨铬钴合金、硅、含碳化钨颗粒的致密基体、氧化铝。涂敷方法有漏斗法、喷镀膜法、侧面供料法、前倾供料法。包复层厚空可达6~7mm;平均硬度从(500g下的KHN)400Kg/mm~2到(100g下的KHN)2000~2300kg/mm~2,随所用包复材料而异。
Laser cladding can utilize flame spray, plasma spray, blast spray coating or direct use of powder or wire. The foil material is melted under controlled conditions with a laser beam to disperse and solidify the dissolved material to form a coating between the cladding and the substrate The combination of gold. The clad material can be a cobalt-based alloy, a stellite, a silicon, a dense matrix of tungsten carbide particles, alumina. There are funnel method coating method, spray coating method, the side feed method, forward dumping feed method. The thickness of the cladding layer is up to 6-7 mm. The average hardness varies from 400 Kg / mm ~ 2 (KHN at 500 g) to 2000 ~ 2300 kg / mm ~ 2 (KHN at 100 g), varying with the cladding material used.
