Boron based ceramic coatings were deposited on steel substrates by high-energy short pulse laser melting. Under conditions of the laser deposition, coatings consisted of boron carbide and boron nitride form a layer that acts as solid lubricant leading to a low coefficient of friction (COF). The COF could be drastically decreased by proper selection of chemical composition of boron based ceramic coatings. Ultimately low COF of 0.03 was registered during dry sliding tests of coatings with addition of different metal oxides (MgO, ZrO₂, Li₂O). Low COF of composite ceramics coatings was attributed to the formation of the BO bond observed by the X-ray photoelectron spectroscopy technique. This bond as the essential component of the internal structure of coatings explains ultralow friction behaviour and remains low even during gradual deterioration of the coating. High quality adhesion of ceramics to steels was explained by reactive phase formation at the steel-ceramic interface, which was confirmed by both transmission electron microscopy and X-ray diffraction.

通过高能短脉冲激光熔化将硼基陶瓷涂层沉积在钢基底上。在激光沉积的条件下，由碳化硼和氮化硼组成的涂层形成一层充当固体润滑剂的层，从而导致低摩擦系数（COF）。的COF可以通过基于硼的陶瓷涂层的化学组成的适当的选择来急剧下降。在添加不同金属氧化物（MgO，ZrO ₂，Li ₂ O）的干式滑动试验中，最终的COF为0.03 。复合陶瓷涂层的低COF归因于B的形成通过X射线光电子能谱技术观察到的O键。作为涂层内部结构必不可少的组成部分，这种结合说明了超低摩擦性能，即使在涂层逐渐劣化的情况下也保持较低的摩擦力。陶瓷与钢之间的高附着力可以通过在钢-陶瓷界面形成反应相来解释，这已经通过透射电子显微镜和X射线衍射得到了证实。
