激光熔覆滑动轴承 Laser Clad Bearing

激光熔覆滑动轴承是以316L不锈钢为基体，通过激光熔覆技术在轴承工作面复合一层硬质合金耐磨层的创新型泵用滑动轴承产品。该产品既保留了316L不锈钢优异的耐腐蚀性能，又通过表面熔覆硬质合金赋予了轴承极高的耐磨性能，是纯硬质合金轴承的经济型替代方案，有效应对硬质合金原材料价格大幅波动带来的成本管控压力。

**产品优势**

相较于传统纯硬质合金滑动轴承，激光熔覆轴承具有显著的成本优势。硬质合金原材料价格近年来波动较大，采购成本居高不下。本产品通过在316L不锈钢基体上选择性熔覆硬质合金层，在轴承工作面保持硬质合金的耐磨性能的同时，大幅降低了材料用量，综合成本可节约50%~70%。

**工艺特点**

激光熔覆技术以高能量密度激光束为热源，将硬质合金粉末（如镍基碳化钨、钴基Stellite6等）熔覆于316L基体表面，形成与基体呈冶金结合的高性能功能层，结合强度高，无涂层剥落风险。激光熔覆具有能量集中、热影响区小、稀释率低（可控制在5%以下）等优点，熔覆层组织致密、硬度均匀，耐磨性能优异，熔覆层硬度可达HRC 55以上，部分牌号可达HRC 70以上。

Laser-clad sliding bearings are innovative pump bearings manufactured using a 316L stainless steel substrate with a tungsten carbide wear-resistant layer applied to the bearing working surface via laser cladding technology. This product combines the excellent corrosion resistance of 316L stainless steel with the high wear resistance of tungsten carbide, serving as a cost-effective alternative to solid carbide bearings and effectively addressing cost control challenges caused by fluctuations in tungsten carbide raw material prices.

**Product Advantages**

Compared to traditional solid carbide sliding bearings, laser-clad bearings offer significant cost savings. Tungsten carbide raw material prices have experienced substantial fluctuations in recent years, resulting in high procurement costs. By selectively cladding the tungsten carbide layer onto the 316L stainless steel substrate, this product maintains the wear resistance of tungsten carbide on the bearing working surface while substantially reducing material usage, achieving total cost savings of 50%~70%.

**Process Characteristics**

Laser cladding technology uses a high-energy-density laser beam as the heat source to fuse hard alloy powders onto the 316L substrate, forming a high-performance functional layer with metallurgical bonding to the base material—ensuring strong adhesion with no risk of coating spallation. Laser cladding offers advantages including concentrated energy, minimal heat-affected zone, and low dilution rate (controllable below 5%), resulting in dense and uniform microstructure with excellent wear resistance. Cladding hardness can reach HRC 55 or above, with some grades achieving up to HRC 70+.

📞 This is a custom product. Cladding alloy grade, thickness, hardness, and dimensions can be tailored to specific service conditions. Please provide service conditions (media, temperature, load, speed) and installation drawings. Our engineers will recommend the optimal alloy grade and cladding process for your application.
