Enhancing tribological properties of MoSe2/SnSe2/SnSe@C through 2D nanosheets modification of 3D structures
View through CrossRef
This paper has prepared a new type of MoSe2/SnSe2/SnSe@C heterostructure nanocomposites by one-step hydrothermal method and systematically studied by XRD, SEM, and XPS. Furthermore, the tribological behavior of MoSe2/SnSe2/SnSe and MoSe2/SnSe2/SnSe@C heterojunction in pure oil was extensively examined in a ball-on-disk tribometer. The effects of applied load and rotational speed were also investigated. Compared with MoSe2/SnSe2/SnSe nanocomposites, MoSe2/SnSe2/SnSe@C achieved better friction properties. Especially, when the mass ratio of MoSe2/SnSe2/SnSe@C in the base oil is 1.5 wt%, the friction coefficient reaches the minimum value of 0.1. The results show that the introduction of carbon material can significantly improve the wear reduction and anti-wear properties of the matrix in lubricating oil. Additionally, the construction and excellent tribological properties of MoSe2/SnSe2/SnSe@C heterojunction would be beneficial for the design of novel nano-additives with 2D/3D structure for enhancing friction reduction and anti-wear, which also would expand their actual applications in the industry and agriculture.
