Processing and Fabrication of CuSn10 Powder

Once CuSn10 powder has been produced, it can be further processed and fabricated into various components and products. These processes involve consolidating the powder particles into a dense solid form and shaping them into the desired geometry.

焼結

• This process involves compressing the powder into a desired shape and then heating it to a temperature below its melting point. The heat causes the particles to bond together, forming a dense solid.
• This technique involves subjecting the powder to high pressure and temperature in a sealed container. The pressure helps to densify the powder and eliminate porosity, resulting in a highly dense and uniform product.

圧縮

• This process involves compressing the powder into a desired shape at room temperature. This method is often used for producing simple shapes, such as disks or cylinders.
• This technique combines cold pressing and sintering in a single step. The powder is compressed at a high temperature, which simultaneously densifies and shapes the material.

Joining Techniques

• This process involves joining CuSn10 powder components using a filler metal that melts at a lower temperature than the base metals. The filler metal flows between the joints and solidifies, creating a strong bond.
• Similar to brazing, soldering involves joining components using a filler metal with a lower melting point. However, soldering typically uses a softer filler metal and lower temperatures.

Other Processing Techniques

• This emerging technology allows for the direct fabrication of complex shapes from powder materials. Techniques such as laser powder bed fusion and binder jetting can be used to produce CuSn10 components with intricate geometries.
• CuSn10 powder components can be subjected to various surface treatments, such as plating, coating, or heat treatment, to enhance their properties or protect them from corrosion.
