硬面堆焊(hardfacing)是一种表面工程工艺,通过在高应力或易磨损的金属部件表面熔覆一层高硬度、耐磨的合金材料,以延长设备使用寿命并降低维护成本。该技术广泛应用于机械制造、能源、采矿等领域。
硬面堆焊的核心原理基于冶金结合技术。根据美国焊接协会(American Wellying Society)的定义,操作时通过电弧焊、激光熔覆或等离子转移弧等方法,将碳化钨、钴基合金等材料熔融在基材表面。这种工艺形成的强化层硬度可达HRC 60以上,显著高于普通钢材(HRC 20-30)。
ASM International发布的《表面工程手册》指出,硬面材料需根据工况匹配性能:
硬面堆焊可使部件寿命提升3-8倍,同时减少70%以上的金属材料消耗。国际标准化组织(ISO 14172)已将该工艺纳入金属焊接规范体系,全球市场规模在2024年达到48.7亿美元(Global Market Insights数据)。
Hard facing 是一个工程领域的专业术语,主要涉及材料表面处理技术。以下是详细解释:
