Abstract:
A presentation on the progress of this contract was made at the 12 April 1988 at the SCORE meeting held at the Ministry of Defence, London. Status: Company only able, in practice, to deposit aluminium at below 900C. Plate specimens treated and metallographic sections prepared. A 25 micron depth of aluminized layer has been formed, of hardness 360 HV 50g. But the high temperature treatment has caused softening of the substrate (from 380 HV to 280 HV 20kg). This a promising result and further plate samples have sent for treatment at differing conditions to ascertain if the hardened layer (of titanium aluminides) can be formed without substrate tempering or whether re- solution treatment will restore substrate properties.
