Evaluating the mechanical and friction-reducing properties of boronized steels and other alloys

在钢和铁合金上涂覆可靠的防护涂层是公认的在井下采油和选矿中提高油管、套管和不同工程部件的耐磨性和耐腐蚀性的途径。作为一种选择，渗硼技术可以成功地应用于此目的。有可能改善摩擦学性能的新涂层需要对摩擦和摩擦腐蚀条件进行广泛的研究，并从涂层的组成和结构方面评估这些性能。耐久技术公司拥有在工业规模上生产钢和黑色金属合金的防护涂层的工艺。然而，为了更好地了解涂层的性能，特别是对于新涂层，还需要进行更多的研究，例如使用/应用条件对结构和材料破坏机理的影响。特别是，重点评估金属的纳米和微观结构将是将磨损率降低到可接受的每小时管道厚度减少量的关键。这些研究将用于进一步开发和优化具有功能性能的涂层，特别是用于摩擦和摩擦腐蚀应用的产品。

Reliable protective coatings on steels and ferrous alloys is the approved route to increase wear and corrosionresistance of tubing, casing and different engineering components in downhole oil production and mineralprocessing. As one of the options, boronizing technology can be successfully employed for this purpose. Newcoatings with potentially improved tribological properties require extensive studies in the friction andfriction-corrosion conditions, as well as the evaluation of these properties with regards to the coatingcomposition, and structure. Endurance Technologies Inc. has the process for producing the protective coatingson steels and ferrous alloys at the industrial scale. However, additional studies are required for the betterunderstanding of the coatings' performance, especially, for new coatings, e.g. the effect of theservice/application conditions on the structure and materials destruction mechanism. In particular, a focus onevaluating the nano- and microstructure of the metal will be critical in reducing wear rates to an acceptablenanometres reduction in pipe thickness per hour of operation. These studies will be used for the furtherdevelopment and optimization of the coatings with functional properties, in particular for the products forfriction and friction-corrosion applications.
