Performance Test

It is an indispensable task to test its performance after electroplating, and only products that pass the inspection can be handed over to the next process. The quality characteristics of the plating include plating thickness, plating adhesion, plating hardness, etc. At Alfa Chemistry, we offer the following testing services:

• Magnetic induction method
  The plating thickness is determined by the amount of magnetic flux that the probe passes through the non-ferromagnetic plating and flows into the ferromagnetic metal substrate.
• X-ray fluorescence method
  X-rays are shot onto the surface of the plating layer, producing X-ray fluorescence. Information on the thickness of the plating layer can be obtained based on the intensity of the energy appearing in the fluorescence spectral lines.
• Other test methods
  In addition to the above test methods, we also have electrolytic method, metallographic method, eddy current method and other plating thickness test methods.

• Bend test
  Bend test is to bend the specimen under external force to see if the plating is peeling or flaking away from the substrate. Any sign of peeling, crumbling, or flaky flaking is considered poor adhesion.
• Heat-quench test
  Heat-quench test relies on subjecting electroplated parts to elevated temperatures to determine the sufficiency of coating adhesiveness. The appearance of flaking or peeling after quenching is a sign of insufficient adhesion.
• Other test methods
  In addition to the above test methods, we also have chisel-knife test, impact test, peel test, burnishing test and other plating adhesion test methods.

• Microhardness test
  Microhardness Testing is a method of determining a material’s hardness or resistance to deformation when test samples are not suitable for macro-hardness. Microhardness testing is ideal for evaluating hardness of surface plating.
• Nanoindentation test
  Nanoindentation is a powerful technique used to quantitatively characterize the mechanical properties of small volumes of material. Nanoindentation testing provides data on the hardness of the plating.
