The journal aims to provide a forum for the disseminations and exchanges of scientific and technological knowledge based on original research works among those linked to advanced coatings study, development and/or production, focusing in different areas such as wear-resistant coatings, corrosion protective coatings, optical protective coatings, films for biomedical and energy purposes, decorative coatings, and others, produced by advanced techniques such as PVD, CVD, thermal projection, etc.</span></span></span></p> Lifescience Global en-US Journal of Coating Science and Technology 2369-3355 <h4>Policy for Journals/Articles with Open Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Authors retain copyright and grant the journal right of first publication with the work simultaneously licensed under a <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank" rel="noopener">Creative Commons Attribution License</a> that allows others to share the work with an acknowledgement of the work's authorship and initial publication in this journal.<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work</li> </ul> <h4>Policy for Journals / Manuscript with Paid Access</h4> <p>Authors who publish with this journal agree to the following terms:</p> <ul> <li>Publisher retain copyright .<br /><br /></li> <li>Authors are permitted and encouraged to post links to their work online (e.g., in institutional repositories or on their website) prior to and during the submission process, as it can lead to productive exchanges, as well as earlier and greater citation of published work .</li> </ul> https://www.lifescienceglobal.com/pms/index.php/jcst/article/view/10791 <p>A new indirect-analytical method for determining the external specific surface area of high-strength synthetic diamond grinding powders has been created. The method is based on the well-known from publications fractional-averaging approach to the indirect analytical determining of technological properties of high-strength synthetic diamond grinding powders. The main idea of the proposed new method is to take into account the features of the real 3D morphology of grains of such grinding powders. The possibility and expediency of using in similar problems in one sense of calculation, both a methodological scheme with an extrapolation-affine 3D grain model and a methodological scheme with actual 3D grain shape, have been substantiated. The proposed methodological scheme allows for the real morphology of grains of such grinding powders to be considered, which provides greater reliability of the indices of their technological properties obtained. The practical application of the proposed new method for determining the external specific surface area of the standard Ukrainian State Standard DSTU 3292–95 high-strength synthetic diamond grinding powder AC400 500/400 is illustrated. The new method we proposed was used as the basis for comparison. The value of the external specific surface area of the specified grinding powder calculated by this method was 4.3213 m²/kg. Applying the commonly used method for this purpose gave the result of 4.1324 m²/kg. The comparative analysis showed that the commonly used known method gives 1.046 times (4.37%) lower values of the external specific surface area for the specified grinding powder than the proposed new method. This indicates the advantage of the proposed new method for determining the external specific surface area of high-strength synthetic diamond grinding powders.</p> Grigorii A.
