This capability supports a functionally different material coating method. The process mainly focuses on a slurry-based coating method, which is an inexpensive and easy coating method similar to paint, screen printing, dip coating, and spray coating. This functional coating can be used to create electrical, corrosion, and heat-resistant coating on sheet or bulk material followed by heat treatment.
Ink or paste can be controlled via their surface tension and viscosity. Print is on the surface of material and heat treatment. During heat treatment, designed phase or material can be obtained. Normally, there is no special size limitation for samples, except printing equipment size limitations. PNNL has an ultrasound spray coating machine, high-temperature differential scanning calorimetry (DSC) (1,600°C), furnaces, a dry oven, dip coating equipment, a screen-printing machine, and paint blush.
Metal-metal and ceramic-metal coating can be done. This coating helps protect from corrosion circumstances and can offer special function (as needed). High- or low-temperature materials can be coated easily.
Facilities are available for both government and private (proprietary) project work.
