The physical performance experiment refers to the experiment conducted on the physical characteristics of the coating, the substrate or the plating solution, and the indicators usually involved are physical indicators, such as the electrical properties of the coating or the substrate,
Mechanical properties and coating bonding force, brittleness, surface morphology, roughness, etc. Physical experiments generally do not involve changes in material properties, but only changes in physical state (molecular aggregation state) and surface morphology. Some physical experiments only use samples as carriers to test their conduction properties, such as electrical conductivity and magnetic permeability. etc. At this time, the sample itself does not undergo any changes.
The chemical performance experiment is an experiment related . In the process of chemical experiments, chemical reactions generally occur, or are accompanied by energy conversion and changes in material properties, such as anti-discoloration performance experiments, corrosion resistance experiments, porosity detection, analysis of plating solutions, anodes, chemical raw materials, etc. Laboratory tests, etc. Except for a few chemical experiments where only the tools involved in the detection change (such as the determination of pH value, etc.), the properties of the samples in most chemical performance experiments will change, which are basically destructive. Various chemical changes such as dissolution, discoloration, precipitation, oxidation reaction or reduction reaction will occur. Therefore, when conducting chemical performance experiments, it is necessary to prepare , and then ensure that there are enough data to make the experiments can be carried out normally.
