80%以上机械零部件的失效通常由表面磨损与腐蚀而引起,由此造成的损失每年合计可达到国民生产总值的10%以上,因此通过各类表面工程技术将具有优越耐腐蚀或耐磨损性能的材料覆于满足承载能力要求的普通结构件表面,构筑复合结构材料已经成为提高机械零部件服役效能、零部件附加价值与产品核心竞争力的重要方法。热喷涂技术是表面工程技术中,灵活性高、易于自动化加工、适应性强的重要表面工程技术之一,所产生的产值约
Over 80% of the failure of mechanical components is usually caused by surface wear and corrosion, resulting in a total annual loss of more than 10% of GNP, so through a variety of surface engineering technology will have excellent corrosion resistance or wear Damage performance of the material to meet the carrying capacity requirements of the ordinary structure of the surface, the construction of composite materials has become a mechanism to improve the service performance of mechanical parts, spare parts added value and product of an important method of core competitiveness. Thermal spraying technology is one of the important surface engineering technologies with high flexibility, easy automation and adaptability in surface engineering technology. The output value
