Is there a way to improve the wear resistance of PET gold-plated film?

PET gold-plated filmAs a composite material that combines the flexibility of PET substrate with the conductivity and corrosion resistance of gold layer, it has shown wide application prospects in multiple fields such as electronics, packaging, and decoration. However, in practical use, the wear resistance of PET gold plating film becomes one of the key factors affecting its service life and performance stability. This article aims to explore feasible methods for improving the wear resistance of PET gold plating film, and cites relevant research and practice from Advanced Institute (Shenzhen) Technology Co., Ltd., combined with reference data and experimental data for in-depth analysis.

The Challenge of Wear Resistance of PET Gold Plated Film

PET gold-plated filmAlthough it has many advantages, its wear resistance is affected by various factors, including the thickness of the gold plating layer, the quality of the substrate treatment, and the usage environment. Insufficient wear resistance may lead to coating detachment and increased scratches, thereby affecting the appearance and performance of the product.

Methods to improve the wear resistance of PET gold plating film

1. Optimize the surface treatment of the substrate

The cleanliness and flatness of the substrate surface directly affect the adhesion and wear resistance of the coating. Through advanced surface treatment techniques such as plasma cleaning and chemical etching, impurities such as grease and dust on the substrate surface can be effectively removed, increasing the adhesion between the coating and the substrate, thereby improving wear resistance.

Comparison of experimental data:

• Untreated substrate: After wear resistance testing, the coating detachment rate is about 10%, and scratches are obvious.
• After plasma cleaning treatment of the substrate, the wear resistance test showed that the coating detachment rate decreased to 2% and scratches were significantly reduced.

2. Increase the thickness and hardness of the coating

Increasing the thickness of the gold plating layer within a certain range can improve its wear resistance, as thicker coatings can better resist external friction and scratching. At the same time, by adjusting the composition of the plating solution and electroplating process parameters, such as current density, electroplating time, etc., the hardness of the coating can be further improved and its wear resistance can be enhanced.

Comparison of experimental data:

• Standard thickness gold plating layer (25 μ m): After wear resistance testing, the scratch depth is about 0.5 μ m.
• Thicken the gold plating layer (50 μ m) and optimize the hardness: After the wear resistance test, the scratch depth was reduced to 0.2 μ m.

3. Use wear-resistant coatings or additives

Coating a wear-resistant coating on the surface of the gold plating layer, or adding wear-resistant additives to the plating solution, is another way to improveWear resistance of PET gold-plated filmEffective methods. Wear resistant coatings can form a protective barrier to resist external wear and tear; Wear resistant additives can form hard particles in the coating, enhancing its wear resistance.

Comparison of experimental data:

• Non wear-resistant coating PET gold plating film: After 500 friction cycles, obvious scratches appear on the surface.
• Coating with wear-resistant PET gold film: After 1000 friction cycles, the surface still maintains good condition with slight scratches.
