The surface treatment technology of fasteners has the following development trends:

Environmental Protection:

Clean production: adopting green chemical processes such as laser surface modification to reduce or avoid the use of toxic and harmful chemical reagents, and reduce the discharge of wastewater, exhaust gas, and waste residue.

Resource recycling: Improve the recycling rate of coating materials, develop recyclable surface treatment technologies, and reduce resource consumption.

High performance:

Extreme environment resistance: Develop coating or treatment technologies that can adapt to extreme working conditions such as high temperature, low temperature, strong corrosion, and high radiation, such as surface treatment of fasteners used in aerospace and deep-sea equipment.

Multi functional integration: enables the surface treatment of fasteners to have multiple functions, such as good corrosion resistance, wear resistance, conductivity, self-lubricating properties, etc., to meet complex application requirements. Nanocomposite coating technology can achieve multifunctional integration by adding nanoparticles with different characteristics.

Precision and Localization:

High precision processing: For miniaturized and precision fasteners, such as micro screws in electronic devices, surface treatment techniques such as ion implantation without dimensional deformation and high precision will be more widely applied.

Local performance optimization: Using laser surface modification and other technologies to achieve precise processing of specific parts of fasteners, while not affecting overall performance, to improve the performance of key parts in a targeted manner, such as locally strengthening the threaded parts of the fastening bolts at the root of aircraft engine turbine blades.

Intelligence and Automation 3:

Production process control: With the help of sensors, the Internet of Things, and artificial intelligence technology, real-time monitoring and optimization of surface treatment processes are achieved to achieve automated parameter adjustment and quality control, improving production efficiency and product consistency.

Intelligent Quality Inspection: Using intelligent detection equipment and algorithms, such as machine vision based surface defect detection systems, to quickly and accurately detect quality issues on the surface of fasteners and promptly identify non-conforming products.

Multi process integration: A single surface treatment process is difficult to meet complex requirements, and the combination of multiple processes will become a trend. For example, first perform electroplating or chemical plating to form a basic coating, and then optimize surface properties through ion implantation; Alternatively, laser surface modification can be combined with nanocomposite plating to leverage their respective advantages and achieve a more comprehensive surface treatment effect.
