Ultrasonic deicing is a new method of deicing. This paper analyzed and designed a kind of ultrasonic deicing acoustic system, then simulated it with the ANSYS, which is a kind of finite element simulation computer software used to do finite element simulation work. The results indicate that the frequency and mechanical properties of the acoustic system meet the expectant demand.

Si Content

In this work, Si-doped DLC films were deposited on stainless steel (316SS) and polycarbonate (PC) substrates by RF-PACVD in gas mixtures of SiH4+CH4, with 2, 5 and 10 vol.% SiH4. The increase of the Si content in the films led to a progressive drop in the hardness from 30 GPa down to 23 GPa whereas the elastic modulus increased from 124 GPa up to 146 GPa, as measured in the SS coated substrates. In the case of coated PC samples pop-in was observed in the loading curve which was interpreted by finite element simulation and nanoscratching techniques.
