总体来说,热喷涂工艺对工件大小没有太大的限制,但工件的尺寸和形状会直接影响工艺选择、实施的难度和成本。我们可以从“能喷多小”和“能喷多大”两个角度来理解,并且工件的形状也是一个重要因素。一、对“小工件”的考量小工件(如螺丝、刀具、小型轴、医疗器械零件)的主要挑战在于 夹具设计、热管理和涂层均匀性。1、夹具设计:需要设计细致且耐用的夹具来牢固地夹持小工件,并确保其在高速旋转或喷枪移动时不会脱落或变形。同时,夹具要尽可能小,以避免遮挡喷涂区域。2、热管理(关键因素):小工件的热容量小,在喷涂火焰或等离子射流的高温下,温度会迅速升高。过高的基体温度会导致:3、基体热损伤:如退火,导致硬度下降。4、涂
Laser cladding and supersonic spraying (mainly HVOF/HVAF) are both advanced remanufacturing technologies, but they are fundamentally different in principle, performance and application scenarios. This paper explains why laser cladding is usually the preferred solution in roller repair.I. Core differ
Zirconia coating is a widely used surface treatment technology in the industrial field, and its effectiveness has been verified in multiple aspects. Firstly, zirconia coatings perform exceptionally well in terms of corrosion resistance. Compared with other coatings, zirconia has excellent oxidation
