This specification covers thermal spray processes for original equipment manufacturers (OEMs) and the repair of machinery components. The scope includes (1) recommended applications, (2) management and engineering requirements, (3) equipment and facility requirements, (4) feedstock materials, and (5) application processes for thermal spray coatings.

The thermal spray processes covered by this standard are combustion and high velocity oxygen fuel powder, electric arc, and plasma processes that use either powder or wire as feedstock.

Development of this standard was initiated at the request of the U.S. Navy to replace MIL-STD-1687A (SH), Thermal Spray Processes for Naval Ship Machinery Applications. It contains Annex B that the Navy may still use as their guide for surface ship applications. Annex B also lists Navy applications that are permitted and those that are prohibited, including the certification, approval requirements and protocols for handling U.S. Navy components.

Others may use this standard and annexes as a guide to establishing contract document requirements between equipment owners (purchaser) and thermal spray coating contractors where they may choose to invoke all or only a portion of this specification’s requirements as fits the needs of their work.
