Initial Assessment of CSA Group Niobium Boron Based Coatings on 4340 Steel

Abstract

Three (3) samples were received from CSA Group for initial assessment of coating properties. The specimens were arbitrarily labeled as CSA-1, CSA-2, and CSA-3. The vendor also supplied two (2) metallographic mounts reported as (1) thin and (2) thick Niobium-Boron (Nb-B) type coatings on steel. CSA Group is interested in providing coatings for potential electroplated Cr replacement. The group reportedly has the capability to deposit refractory metals on steel. The Army has interest in Cr replacement technologies both for performance and environmental considerations. This initial assessment is intended to determine applicability of the coatings for protection of high-strength steel.
