the use and/or operation of metal components occurs in many different environments. The environments differ a lot and some of them cause significant effect on the metal. Effect may be caused by high temperatures or corrosive elements. Functionality, aesthetic value, and durability among other aspects get affected diversely by such adverse conditions. These effects led to research that led to the invention of diffusion coatings. These kinds of coatings are meant to offer protection to substrates against damage that results from environmental effects. This article will discuss the process and how protection is offered.
The process of applying a diffusion coating on a metal substrate is called diffusion coating too. This process is done inside a chamber at temperatures that are very high. Various metals such as nickel, iron, and cobalt are activated thermally during the procedure. Before the process can start, the substrate needs to be cleaned thoroughly first. Cleaning can be done through various methods, but abrasive blasting is commonly used. Cleaning is for removing dirt and other undesirable materials from the surface of substrates.
After being properly cleaned, the substrate is placed in a special container, which is placed inside a furnace in turn. The furnace is sometimes called a chamber. The furnace operates at very high temperatures, which range between 380-425 degrees.
When certain temperatures are attained within the aforementioned range, diffusion occurs to the metal. This makes it to make an alloy with the substrate. The nature of the substrate and the kind of metal used dictate how much time this process can last. However, most processes last from two hours to four hours. The substrate must be continuously turned throughout the process to achieve equal thickness.
The smoothness of the resultant coating is high while the thickness if uniform. Thicknesses can be varied to suit different functions. However, 15-80 micrometers is the normal range of thickness. The coating resembles the metal used in color. Iron, cobalt, chromium, aluminum, and silicon are some among the commonest metals in use. Various metals such as iron, steels, cobalt, and nickel can be coated.
The coating that results is capable of resisting erosion, oxidation, and reaction with substances like air and water. Metal components that are used for critical functions are made stronger, more durable, and more reliable. Gave valves, pump impellers, power generation components, and gas turbines engine constituents including vanes, blades, and cases are among the components that are coated this way.
The use of this process is mostly confined in industrial settings. Very few household devices incorporate this process in their production. The invention of the process happened several years ago and it has been undergoing modification over time to achieve perfection. Currently, better methods and technology exist.
Modern furnaces incorporate several important features that make them more effective and functional. The improved functionality and efficiency allows for the attainment of thin coats that last longer and are stronger, while offering good protection at the same time. The employment of this technology seems to be higher in automobile industry.
