Which of the following is the advantage of using the electron beam melting technology?(a) Low cost(b) Good surface finish(c) Low maintenance(d) Negligible impurities |
|
Answer» The correct answer is (d) Negligible impurities Explanation: Electron beam melting is a vital technology in industries. This method has many advantages like high strength properties of metal, high energy level and the most important is the negligible impurities in the metal parts, because this process uses a vacuum chamber that eliminates the all kind of impurities like oxides, nitrides etc. |
