Magnesium silicate hydroxides (MSHs) with granular, schistose, and tubular morphologies were separately incorporated to enhance the tribological properties of phosphate/MoS₂ composite coatings. The nano-schistose MSH demonstrated superior tribological performance due to its effective interactions with the worn surface and frictional synergies with solid lubricants. Incorporation of nano-schistose MSH decreased the friction coefficient of composite coatings by about 34.7% and increased the anti-wear performance of composite coatings by about thirteen times. Nano-schistose MSH facilitated the formation of a friction-induced multi-layer heterogenous slipping structure with layered solid lubricants at the friction interface. Moreover, tribo-chemical reactions between nano-schistose MSH and worn surface promoted the in-situ formation of a cermet supporting film, and this also induced the gradual in-situ formation of a lubrication film on the top of worn surface. Consequently, the contact state between tribo-pairs was timely regulated and the invalidation of the nanocomposite slipping structure was effectively restrained during the friction process. As a result, the service life of the phosphate composite coatings was significantly extended and further abrasion on the worn surface was notably reduced.

分别掺入具有粒状、片状和管状形态的氢氧化硅酸镁(MSH)，以增强磷酸盐/MoS ₂复合涂层的摩擦学性能。纳米片状 MSH 由于其与磨损表面的有效相互作用以及与固体润滑剂的摩擦协同作用而表现出优异的摩擦学性能。纳米片状MSH的掺入使复合涂层的摩擦系数降低了约34.7%，复合涂层的耐磨性能提高了约13倍。纳米片岩 MSH 促进了摩擦诱导的多层异质滑移结构的形成，并在摩擦界面处形成了层状固体润滑剂。此外，纳米片状MSH与磨损表面之间的摩擦化学反应促进了金属陶瓷支撑膜的原位形成，这也导致了磨损表面顶部润滑膜的逐渐原位形成。因此，及时调节了摩擦副之间的接触状态，有效抑制了纳米复合材料滑移结构在摩擦过程中的失效。结果，磷酸盐复合涂层的使用寿命显着延长，磨损表面的进一步磨损显着减少。
