ISO/TR 14232-2:2017 PDF

Overview

ISO/TR 14232-2:2017 - Thermal spraying - Powders - Part 2 provides evidence-based guidelines for selecting spray powder chemistry (metals, ceramics, cermets) to achieve objective coating performance. This technical report does not set normative requirements but consolidates academic literature (notably the Journal of Thermal Spray Technology and International Thermal Spray Conference proceedings) into practical comparison tables mapping wear resistance and corrosion resistance needs to powder compositions. It complements ISO 14232-1 (powder characterization) and replaces the earlier ISO 14232:2000.

Key topics

• Purpose: guidance for selecting powder chemistry/composition to meet specified coating performance.
• Comparison tables:
  • Table 1 - Correlates types of wear (abrasive, adhesive, chemical, erosion, fretting, impact, rolling, sliding) with recommended powder chemistries and powder composition examples (metals/alloys, ceramics, cermets).
  • Table 2 - Maps corrosion environments (acid/alkaline/salt, atmospheric, biochemical, sea/fresh water, combustion gas, molten metal/salt, steam, soil, etc.) to suitable coating chemistries and powder formulations.
• Powder families covered: metallic alloys (e.g., stainless steels, Ni/Co-based), ceramics (Al2O3, TiO2, ZrO2, Cr2O3, YSZ), and cermets (WC-Co, Cr3C2–NiCr, TiC-based).
• Basis and scope: summarises peer-reviewed studies and conference findings; focuses specifically on wear and corrosion performance (other performance categories are indicated as in preparation).
• Document type: Technical Report (TR) - informative, no normative references listed.

Applications

ISO/TR 14232-2:2017 is practical for:

• Coating/material selection - helping engineers choose spray powders to meet wear and corrosion service conditions.
• Specification writing - supporting procurement and QA teams with performance-driven powder chemistry guidance.
• Process development & R&D - informing thermal spray process tuning (HVOF, plasma, wire-arc) and material trials.
• Failure analysis & maintenance - selecting remedial coatings for erosion-corrosion, seawater, combustion gas, or food-contact environments.

Typical sectors that benefit include marine/offshore, power generation, chemical processing, transportation, industrial machinery, and food processing where wear and corrosion resistance matter.

Who should use this standard

• Materials and corrosion engineers
• Thermal spray specialists and applicators
• Design and maintenance engineers
• Specification authors and procurement professionals
• Researchers comparing coating chemistries and performance
