Microwave Drilling of Ceramics
The microwave-drilling technique using an open-end coaxial applicator was disclosed recently [1-3]. This paper presents new experimental and theoretical results of microwave-drilling studies in various ceramics, including mullite, alumina, and zirconia. The paper reviews the microwave-drill principles and describes the experimental setup and procedures. Aspects of igniting the microwavedrilling...
متن کاملMicrowave Drilling of Ceramic Thermal-Barrier Coatings
The microwave drill is a novel process for creating shaped holes in nonconductive materials. Its inherent material selectivity makes the microwave drill ideally suited for the controlled removal of ceramic coatings from underlying metallic substrates. In this paper, it is shown that the microwave drill process can drill through ceramic thermal barrier coatings (TBCs) to uncover an array of simu...
متن کاملMicrowave Melting and Drilling of Basalts
The paper presents two experimental methods for basalt processing by microwaves, and their results. One method employs a single-mode cavity to melt basalt, and to produce a volcanic glass (obsidian). The other method uses an open-end applicator (i.e. a microwave drill [1]) to form holes in basalt rocks. Experimental observations of the basalt interactions with microwaves in these two schemes ar...
متن کاملMicrowave Propagation in the Upper Troposphere
Ernest P. Manly, W7LHL PO Box 1307 Graham, WA 98338-1307 [email protected] The selection of propagation modes for amateur microwave stations is often progressive. Most of us start with simple equipment and the contacts are usually by line-of-sight propagation. Longer distances are then accomplished by going to high locations. As equipment gets better, the use of various objects for reflection...
