RETRACTED: Tribological analysis of hydrocarbon refrigerants applied to the hermetic compressor

Reason: This article has been retracted at the request of the editor as it is a substantial duplication of a paper that has already been published in Materials and Design, 26 (2005) 578-586. doi:10.1016/j.matdes.2004.08.009. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper is not under consideration for publication elsewhere. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.
