Introduction
Hardware fasteners are widely used in various industries, including aerospace, automotive, construction, and electronics. However, these fasteners are often exposed to harsh environments, such as dust and oil, which can affect their performance and durability. Therefore, it is crucial to study the dust and oil resistance characteristics of hardware fasteners to ensure their reliability and safety.
Research Methods
The research on the dust and oil resistance characteristics of hardware fasteners was conducted through several methods, including experimental testing and numerical simulation. In the experimental testing, the fasteners were exposed to different levels of dust and oil, and their performance was evaluated based on various parameters, such as torque, tension, and fatigue strength. The numerical simulation was performed using finite element analysis (FEA) to predict the behavior of the fasteners under different environmental conditions.
Research Findings
The research findings showed that the dust and oil resistance characteristics of hardware fasteners are influenced by several factors, such as the type and level of contaminants, the material and surface treatment of the fasteners, and the design and assembly of the joint. The presence of dust and oil can reduce the friction coefficient and increase the wear and corrosion of the fasteners, leading to loosening, failure, and safety hazards. However, the use of appropriate coatings, lubricants, and sealing methods can improve the dust and oil resistance of the fasteners and prolong their service life.
