Abstract
A method of processing BMGs in a non-ideal environment (such as air) to create a uniform and smooth surface is provided. By utilizing the contact-line movement and an engineered flow pattern during TPF the method is able to create complex BMG parts that exhibit uniform smooth appearance or even can be atomically smooth. In addition, to mending surface imperfections, this method also eliminates void formation inside the material, allows for the creation of precise patterns of homogeneous appearance, and forms improved mechanical locks between different materials and a BMG.
