Abstract Four kinds of aviation liquid lubricants (i.e., 4010#, 4050#, 4106#, and 4109# oils) were homogeneously coated on the graphene/MoS2 composite coating through a spin-coating method to form the solid–liquid lubricating combinations. The tribological properties of the obtained solid–liquid combinations and pure graphene/MoS2 coating were investigated experimentally. Effects of the liquid lubricant type on the friction and wear behaviors of the solid–liquid combinations and pure graphene/MoS2 coating were studied at different applied loads and rotational speeds. Within the ranges of the applied load varying from 10 to 50 N and rotational speed varying from 750 to 1500 rpm, the presence of the above-mentioned liquid lubricants significantly reduces the friction coefficient of the pure graphene/MoS2 coating, and the reduction rate is as high as 24%. Additionally, the coating-4109# combination has the best synergistic effect under the above operation condition.

A new kind of UV-responsive film with quantum dots (QDs) fabricated by a spin-coating method is proposed in this paper. In a previous study, the monolayer QDs film is deposited onto fused silica slides by the spin-coating way, which has some luminous problem. The introduction of composite QDs coating which adds PEDOT:PSS and poly-TPD films to the monolayer QDs film is found to have excellent performance. The reason can be that PEDOT:PSS and poly-TPD weaken the scattering and enhance the emitting of quantum dot fluorescence. The intensity of photoluminescence (PL) for composite QDs coating is dozens of times stronger than that for monolayer QDs film. Experiment results show that this composite coating has excellent fluorescent properties and emits a blue purple glow together a wide excitation spectrum field from 190 nm to 300 nm. The spectrum of the composite coating matches accurately with the detected zone of CCD, which achieves an outstanding UV-responsive coating for conventional silicon-based image sensors.

Incorporation of metallic elements, titanium and copper, into carbonaceous mesophase (CM) was performed through mechanical alloying in a ball mill apparatus. The structures of the raw CM as well as the Ti/Cu-added CM were characterized by X-ray diffraction. The tribological behavior of the Ti/Cu-added CM used as lubricating additives was investigated by using a high temperature friction and wear tester. The results show that, compared with the raw CM, the Ti/Cu-added CM exhibits a drop in the crystallinity and a transition to the amorphous. The Ti/Cu-added CM used as lubricating additive displays an obvious high temperature anti-friction and wear resistance effect, and the lager the applied load, the lower the friction coefficient and the wear severity.
