Quality inspection of Nickel Plated Parts is an important part of ensuring that the product meets the predetermined performance standards and customer needs. The following are the main aspects of quality inspection of Nickel Plated Parts:
Appearance inspection of coating
Glossiness: Observe whether the coating surface is bright and uniform, without obvious color difference and uneven gloss.
Surface defects: Check whether there are pitting, cracks, blistering, delamination, nodules and other defects on the coating surface. These defects will affect the appearance quality and mechanical properties of the coating.
Coating thickness inspection
Measurement method: Use handheld thickness gauges, paint thickness gauges and other equipment for measurement. Ensure that the selection of the measurement position is representative, and usually select areas with smooth and defect-free surfaces for measurement.
Thickness standard: Determine the minimum and maximum thickness range of the coating according to product requirements and technical standards. Ensure that the coating thickness meets the specified requirements to ensure the performance and service life of the product.
Coating uniformity inspection
Detection method: Use SEM (scanning electron microscope), EDX (energy spectrum analyzer) and other methods to detect the element distribution and surface morphology of the coating. Through these testing methods, the uniformity and consistency of the coating can be judged.
Uniformity requirements: The coating should be evenly distributed on the entire surface of the part without obvious uneven thickness. This helps to ensure the performance and appearance quality of the product.
Corrosion resistance test
Test methods: Salt spray test, wet heat test and other methods are used to test the corrosion resistance of the coating. These methods can simulate harsh environmental conditions, such as marine, chemical and other environments, to evaluate the corrosion resistance of the coating.
Corrosion resistance requirements: According to product requirements and technical standards, the corrosion resistance level of the coating is determined. Ensure that the coating can still maintain good corrosion resistance in harsh environments to ensure the service life and reliability of the product.
Adhesion test
Test methods: The grid method, cutting method and other methods are used to test the adhesion between the coating and the substrate. These methods can evaluate whether the coating is easy to fall off or peel when subjected to external forces.
Adhesion requirements: There should be good adhesion between the coating and the substrate to ensure that the product will not be affected by the shedding of the coating during use. Its performance and appearance quality.
