Abstract

In some cases which are unable to replace the inserts when the depot maintenance or performance improvement of armored vehicles are carried out could have a risk of declining clamping forces by re-processing chromate. The change in the clamping forces of inserts has been investigated by applying a chromate process to hold the insert on the aluminum plate of the armored vehicle in this paper. In order to identify the effect of types and surface treatment, the breaking strength has been measured by the equivalent test item to the actual conditions. These tests would contribute the establishment of the armored vehicle production process.
