---Thermal spraying application is not limited by the size of the workpiece or component, and can be fixed or mobile according to the spraying process; ---With appropriate equipment, even parts with complex geometric structures can be thermally sprayed; ---The paint has high adhesion on the surface of the untreated thermal spray coating; --- When the thermal spraying process and thermal spraying materials are different, different coating thicknesses can be used, but at present it is considered that the minimum thickness should not be lower than 10 μm: Thermal spraying has the following disadvantages: --- If the thermal spray coating is not subjected to subsequent heat treatment, its bonding mechanism is mechanical bonding, so its bonding strength is limited; ---The bonding strength between the coating and the base material will be affected by the difference in thermal expansion coefficient between the two, especially when the workpiece temperature is high , the impact is more pronounced; ---Thermal spray coating is a microporous structure; ---The thicker the thermal spraying coating, the higher the residual stress of the coating, and the multiaxial stress increases accordingly; --- If the thermal spray coating is not subjected to subsequent heat treatment, its ability to withstand sharp point, local, line contact loads, and impact forces is limited; --- The application of thermal spraying is also limited by the geometric size of the workpiece, such as thermal spraying cannot be performed on the inside of a workpiece with too small inner diameter: Thermal Spray Thermal Spray Application Guide1 ScopeThis document provides a general guideline for the preparation of metal, cermet, oxide ceramic and plastic coatings by thermal spraying on metallic and non-metallic substrates: General guidelines, appropriate and available thermal spray equipment, proper operation, monitoring, quality assurance, and guidelines for non-destructive or destructive testing of test specimens or workpieces Recommendations, describing problems that can arise during thermal spraying and ways to avoid them: This document applies to a variety of general thermal spray applications: This document does not apply to the evaluation of the allowable coating load and quality level, which are related to the application conditions:2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text: Among them, dated references For documents, only the version corresponding to the date is applicable to this document;
