This guide covers the application of thermal spray coatings (TSC) for the protection of steel with aluminum, zinc and their alloys, mixtures, and composites. This scope of this guide includes the major elements of an industrial process instruction covering job description, safety, consumable materials, surface-preparation and thermal spray equipment, quality control (QC) equipment, TSC operator training and qualification, a step-bystep surface preparation and thermal spraying application method with quality control checkpoints, maintenance and repair of thermal spray coatings, and a job control record. Nominal TSC feedstock spray rates and coverage information for a common planning base are presented for purchasers and contractors. A TSC selection guide for various service environments and the operator quaiification requirements are presented in appendices. This guide is modelled on the thermal spray method of MIL-STD-2138A(SH), Metal Sprayed Coating Systems for Corrosion Protection Aboard Naval Ships.¹
