Severe General Corrosion on Historic Lane Plate Made From Chromium Steel
A large portion of the four-hole Lane plate disintegrated and consisted mainly of corrosion products after remaining in the body for 26 years. Transformation structures and carbides were exhibited by the plate which was made from chromium steel. Minimal corrosion was exhibited by the soft austenitic 304 stainless steel used to make the screws. The corrosion products of the plate were revealed by microprobe analysis to impregnate the surrounding tissues. Improper material selection was concluded to be the reason for the general corrosion behavior.
