Research on solid film lubricant and its failure for seeker valve
Abstract
Purpose
The seeker value is a crucial part of a navigation system, able to adjust the nitrogen airflow of the system so as to manipulate guiding and tailing movement. The paper aims to determine the causes of failure of the valve system.
Design/methodology/approach
In order to reduce friction and ensure the smooth operation of the valve, a new MoS2 solid film lubricant cured at room temperature, was coated on the plunger surface of the valve. SEM, EDS, and FTIR analysis was conducted.
Findings
Through analysis it was found that the lock failure of the valves was caused by the absence of MoS2 in the surface and softening and melding of the film at an extended electrifying.
Originality/value
The paper outlines the strategies to avoid lock failure – by improving the quality of the solid film lubricant and modifying the assembly process of the valve.
