A quick-retrieval high-speed digital framing camera [PDF]

open access: yes, 1993
A new high-speed digital framing camera is described. The design is built around a rotating polygon mirror that provides a framing rate of 24 000 frames/s. The camera electronics digitizes an image into a 32×104 grid of pixels, where the second dimension

Radiation Transfer in Arc Plasmas

open access: yesPLASMA PHYSICS AND TECHNOLOGY, 2017
In this paper, attention has been given to the absorption properties of the arc plasma at the different pressure conditions. Calculations of the absorption coefficients for a thermal plasma have been performed as a function of the temperature and the frequency. Methods for prediction of the average absorption coefficients were described and compared in

Plasma-transferred arc-welded composite hardfacings with ZrB2 and TiC reinforcements [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
The traditional approach to prolonging the lifetime of wear parts is to use wear-resistant materials. One such material is hardfacing, which, in addition to its primary function, contributes to sustainability objectives by preventing the failure of wear ...
