To investigate the effect of initial surface roughness on performance at stage current-carrying friction an elastic pair, experiments were conducted using a self-made and wear tester. The results indicate that under experimental conditions, lifespan pair decreases as load decrease. When is Ra 0.2 μm 0.025 N, longest, reaching 320 cycles, with average contact resistance 0.045 Ω standard deviation 0.009 Ω. During normal service period main mechanism furrowing. As adhesion tearing occur,...
Given the significant impact of initial surface layer materials on their tribological performance, this study uses a wire–plate reciprocating friction pair to investigate effects mechanical rolling process elastic current-carrying performance. The plate specimens were subjected processing with varying feed rates under different load conditions, using self-designed and wear testing machine. results show that as rate increase, contact resistance varies within range 0.0065 Ω 0.0310 Ω, standard...
In response to the need optimize performance of copper–graphite current-carrying friction materials, spark plasma sintering (SPS) technology was used prepare composite materials with different graphite orientations. A self-made testing machine study effect orientation on composites. The results showed that as increased, composites initially improved and then deteriorated. optimal when 7.5 wt% graphite–copper 90°, primarily constrained by wear rate. main mechanism furrowing, enrichment...
The media play an important role in health promotion and disease prevention, while at the same time, a variety of mixed messages are beginning to pose new challenges them. However, there is lack literacy (MHL) assessment tools China. Therefore, purpose this study was translate Media Health Literacy (MeHLit) questionnaire into Chinese assess its psychometric properties.This cross-sectional conducted from October December 2022, methodological translation validation MeHLit conducted.As result...
