【 摘 要 】

Friction and wear of 10 types Ni chemical coatings, with and without heat treatment, containing nano-diamond particles of various size – 0;5 nm; 100 nm; 200 nm and 250 nm, are studied in the paper. Procedure and laboratory device for friction investigation in starting regime were developed. Experimental results for the influence of the particle size on the static friction force and the change of friction coefficient have been obtained. Abrasive wear has been studied by means of the procedure developed by the authors for the study of above coatings under conditions of dry friction on surfaces with fixed abrasive. The obtained results are related to the parameters linear wear, wear rate and wear-resistance. A part of this study is connected with the tasks on the 7 FP Project „Acom In (Advanced Computing Innovations)” coordinated by the Institute of Information and Communication Technologies at the Bulgarian Academy of Sciences, and the other part is carried out under the Project ДУНК-01/3 “University R&D Complex for innovation and transfer of knowledge in micro/nano-technologies and materials, energy efficiency and virtual engineering” funded by the Bulgarian Ministry of Education and Science.
