Thermal Diffusion, also known as TD coating, is a green process. This means it comes without any of the environmental issues surrounding other high performing surface protection processes, such as zinc nickel. This process is used for many industrial applications across numerous industries, including aerospace and the marine sectors. Thermal diffusion offers enhanced corrosion resistance that is superior to hot dip galvanising.
Thermal diffusion is the process of diffusing zinc into steel at very high temperatures. This is to form an anti-corrosive alloy layer at the surface of the steel, which is an extremely robust coating. The specific properties of the TD coating, such as thickness and composition, can be tailored to meet exact requirements.
