Author:Masina, Bathusile N; Forbes, ADate:2010Industrial diamonds are heated by a laser beam and the resulting temperature is optically measured on the surface of the diamond. The ultimate aim is that with the heating and temperature known and measurements being repeatable, the ...Read more
Author:Masina, Bathusile N; Forbes, A; Bodkin, R; Mwakikunga, Bonex WDate:Sep 2010In this poster the authors discussed the ability to heat an industrial diamond sample by means of optical absorption of a CO2 laser beam, and then measure the resulting temperature on the surface of the diamond optically by means of radiometry ...Read more
Author:Masina, Bathusile N; Forbes, Andrew; Mwakikunga, Bonex W; Bodkin, RDate:May 2011At present it is known that diamond tools degrade with time as it is normally used at high temperatures. One of the questions the authors like to answer in this study is whether thermally induced problems in diamond tool arise as a result of ...Read more
Author:Masina, Bathusile N; Bodkin, R; Mwakikunga, Bonex W; Forbes, ADate:Aug 2011This paper presents an implementation of a laser beam shaping system for both heating a diamond tool and measuring the resulting temperature optically. The influence the initial laser parameters have on the resultant temperature profiles is ...Read more
Author:Masina, Bathusile N; Forbes, ADate:Sep 2010This presentation acknowledges that temperature induces damage in the diamond bits due to friction during the drilling process. The temperature of the diamond sample can be raised by laser heating it.Read more
