Abstract
A pin comprising a conical body having a central axis and a cross-sectional area that decreases with distance from a first end to a second end. A coating applied to the conical body has a melting temperature that is lower than a melting temperature of the conical body. The coating melting temperature is lower than a friction temperature and the body melting temperature is higher than the friction temperature. The friction temperature is achieved at an interface of the pin and a component when the pin is forcibly positioned into the component to repair a defect. The coating comprises a material having a first tensile strength value of a bond formed between the conical body and the component in response to softening and rehardening of the coating.
