COMPARISON OF BABBIT COATING TRIBOLOGICAL CHARACTERISTICS, DERIVED FROM ACTIVATED ARC METAL COATING AND ALTERNATIVE METHODS
The tribological tests for the determination of babbit coating friction coefficient and wear rate that were derived as a result of turbulent molding, gas building-up, plasma spraying and activate arc metal coating were carried out. The results were analyzed in terms of microstructural metallographic analysis.
Key words: antifriction coating, babbit, tribological test, friction coefficient, metallographic analysis, activated arc metal coating, turbulent molding, gas building-up, plasma spraying.

ESTIMATION OF INFORMATION AMBIGUITY ABOUT QUALITY SYSTEM CONDITION
The article covers the estimation of information ambiguity about quality system condition. We presented the results after analysis of reasons that raise difficulties for high economical results achievement because of a quality management system (QMS) creation and certification. We analyzed main approaches and methods for the activity quality rating of a quality management system (QMS)
Key words: quality system, entropy, activity quality rating of QMS, audit.

ESTIMATION OF PRODUCER’S TECHNOLOGICAL SYSTEMS DURING PRODUCT CERTIFICATION FOR OIL AND GAS COMPANIES
We examined a problem of standardization influence in case of conformity assessment on the effectiveness of technological production system by the example of insulating tubing. As a methodic basis of conformity assessment of insulating tubing in accordance with reliability indexes, standard international approach to the choice of methods and means of risk identification and risk estimation for oil and gas companies was applied.
Key words: standardization, certification, oil and gas industry, system control and test, welding, NDT inspection.
