▎ 摘　　要

NOVELTY - The testing machine has a linear reciprocating high-temperature friction testing mechanism including an upper sample test bench (6) for clamping small balls, and a lower sample test bench (3) for clamping a friction sample. A graphene coating heating module is arranged directly below the friction sample, where the graphene coating heating module is provided with a heating cavity having a graphite coating for directly and rapidly heating the friction sample to a set temperature. The graphene coating heating module includes a heating base provided with a concave cavity, where graphene coated silicon plates are arranged at the bottom of the concave cavity. USE - Linear reciprocating high-temperature friction testing machine for heating graphene coating. ADVANTAGE - The graphene coating heating module is provided with the heating cavity having the graphite coating for directly heating the friction sample to the set temperature, thus ensuring fast heating of the friction sample with high efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic perspective view of a linear reciprocating high-temperature friction testing machine.
