Metal infiltration
Metal infiltration is a manufacturing process used to infiltrate a thin coating or layer of metal onto a substrate. Metal infiltration is typically accomplished by melting a material, such as steel, aluminum, or bronze, and applying it to the substrate by vacuum, atmospheric pressure, or high temperature and pressure.
There are various reasons to use metal infiltration: to provide a corrosion-resistant barrier; to improve the properties of an underlying material, such as increased strength or wear resistance; to add a decorative finish; and to join together components, such as brazing.
The process of metal infiltration typically involves immersing a substrate in a molten material. The molten material then penetrates the substrate, typically no more than a few millimeters deep. The molten material may additionally be vacuum or pressure injected into the substrate.
When metal infiltration is used to deposit a corrosion-resistant coating, a layer of corrosion resistant material is typically deposited on top of the metal-infused substrate. This can protect the substrate from oxidation, corrosion and other environmental factors.
The most common method of metal infiltration is through the use of a vacuum. This creates a seal over the surface of the substrate, and a partial vacuum is created inside. The molten material is then injected into the space, creating a vacuum seal and pushing the molten material into the pores of the substrate.
The primary benefit of metal infiltration is that it can create a strong bond between the substrate and the molten material. Depending on the application, the bond may be permanent or temporary. Other benefits include increased strength, wear resistance, and improved corrosion resistance.
Metal infiltration has a wide range of industrial applications. For example, it is often used to build parts and components for high-temperature and/or harsh environments. It is also used to create decorative finishes and to join components together.
Metal infiltration is a cost-effective, efficient, and reliable manufacturing process. It is a versatile method for adding a corrosion-resistant coatings to a variety of substrates, as well as for creating robust bonds between components.
