一、概述自粘性一次喷涂复合粉末(以下简称为一次法粉)是随着热喷涂(焊)粉末的发展而产生的。最初使用的自熔性合金粉末,是采用先喷涂、后重熔的工艺方法,但这种重熔工艺只能对于一般变形要求不高、对基体强度影响妥求不严的零、部件进行修复,而对于一些修复件的变形、基体强度影响要求较严的零、部件,就不宜采用重熔工艺。后来又出现了冷喷涂方法,但由于当时的冷喷涂对同一零、部件的修复要求不一,对与基体的结合要求以及 First, an overview of self-adhesive powder coating composite powder (hereinafter referred to as a method powder) is with the thermal spray (welding) powder generated. The initial use of self-fluxing alloy powder, is the use of the first spray, after remelting process, but this remelting process can only be less demanding for the general deformation of the substrate strength of the less stringent requirements of the repair parts and components , But for some of the deformation of the repair parts, the substrate strength requirements of more stringent requirements of zero, components, it is not appropriate to use remelting process. Later appeared cold spray method, but because of the cold spray on the same zero, parts of the repair requirements vary, and the substrate combination requirements and
