WebNov 12, 2024 · Finite element analysis results show that the graphene coating will generate thermal expansion when electric current is applied, accordingly avoid the direct contact between the metal substrate, and, thus, reduce the interface friction and alleviate the wear degree of interface. However, the normal force fluctuation of the interface may increase. WebApr 5, 2024 · ΔL = αLΔT is the formula for linear thermal expansion, where ΔL is the change in length L, ΔT is the change in temperature, and is the linear expansion coefficient, which varies slightly with temperature. ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α is the change in volume due to thermal expansion.
