Description

Technical Field

[0001] This utility model relates to the field of fixed support technology, specifically a fixed support for a nano-coating bonding strength sample. Background Technology

[0002] Nano-spraying utilizes nanotechnology to spray nanomaterials containing high hardness and high corrosion resistance onto the surface of a workpiece substrate, quickly forming a thin, transparent protective film—a dense nano-coating. This nano-coating prevents raw material erosion caused by surface scratches, and also provides waterproofing, moisture resistance, dustproofing, oil resistance, and chemical corrosion protection. The nano-spraying process is simple, odorless, and widely applicable, making it an environmentally friendly coating with no pollution.

[0003] The bonding strength of a nano-coating is a crucial technical parameter for determining the bond strength (adhesion) between the coating and the substrate material, and it is a very important indicator for testing coating performance. Insufficient bonding strength can lead to reduced coating life and premature failure, or even localized peeling and flaking, rendering the coating unusable. However, before testing the bonding strength of a nano-coating, the nano-coating must be sprayed onto the ends of the workpiece under test. Currently, the standard GB / T8642-2002, "Determination of Tensile Bond Strength of Thermal Spray Coatings," does not provide relevant nano-spraying fixtures. The standard requires three sets of test specimens for the nano-coating bonding strength test. Using conventional single-specimen spraying, the workload is high, and the uniformity of the nano-coating sprayed onto the ends of the test specimens is difficult to control. Therefore, it is necessary to design a nano-coating bonding strength specimen fixing bracket that can quickly and uniformly spray the nano-coating onto the test specimens, while ensuring the reliability and accuracy of the nano-coating bonding strength test results.
