| Abstract Scope |
The wettability and surface energy of materials is important to understand because it demonstrates the tendency of a liquid material to spread across solid surfaces. The more easily a liquid spreads across the solid, the higher the wettability and surface energy of that surface. This spreading of liquids is vitally important in the use of binder jet printing, where the metal powder is held together by a binder material. To ensure that the metal powder and binder material adhere together, the metal powder must be adequately wetted by the binder. The KRUSS Drop Shape Analyzer 100 allows for the examination of contact angles and surface energy for both solid surfaces and powder materials. Various particle size distributions powders and sands will be examined with water and with the binder material to determine wettability, while the surface energy will be determined using water and diiodomethane. |
