ARO Coatings for Mechanical Protection

In industries where wear is an inherent part of the process such as Oil & Gas, mining, HDD, and bulk solids handling abrasion, particle erosion, and repetitive impact accelerate steel wall loss, increase intervention frequency, and drive up maintenance costs.

High-Performance Surface Protection for Critical Assets Exposed to Extreme Mechanical Service

Aplika Control Corrosión supplies and technically supports ARO (Abrasion Resistant Overlay) coatings that act as sacrificial layers or reinforcement systems. These coatings are designed to withstand abrasion, erosion, and mechanical impact, protecting the metallic substrate under severe operating conditions. The objective is to stabilize wear rates, extend component service life, and improve operational continuity.

Technical Selection Based on Wear Mechanism and Asset Criticality

An effective ARO system is defined based on the dominant damage mechanism and real operating conditions. At Aplika, system selection is supported by applied engineering criteria, considering variables such as contact pressure, relative velocity, particle type, component geometry, and service environment.

Representative Applications

• Horizontal Directional Drilling (HDD): Protection of pipelines exposed to contact with soil, rocks, and bentonite-based drilling fluids during installation, pullback, and recovery operations.
• Solids Transport and Handling: Elbows, pipelines, hoppers, chutes, conveyors, and areas subjected to high friction.
• Impact-Loaded Equipment: Discharge points, equipment exposed to repetitive impacts, or dynamic loading conditions.
• Localized Reinforcement and Repair: Restoration of geometry and protection of recurring wear zones, integrated into corrective and predictive maintenance programs.

Technical Support and Validation Under Real Operating Conditions

At Aplika, coating supply is complemented by specialized technical support to ensure real in-service performance:

• Evaluation of wear type and severity including abrasion, erosion, impact, or combined mechanisms.
• Selection of the ARO system based on mechanical, thermal, and chemical process conditions, as well as the expected wear regime.
• Definition of application criteria including compatible surface preparation, anchor profile, and recommended thickness.
• Technical supervision, quality control, and post-application validation under real operating conditions.
• Recommendations for future maintenance focused on inspectability and reapplication capability.

This approach reduces the risk of premature failure, minimizes rework, and enhances operational reliability in demanding industrial environments.

When Wear Is Inevitable, Technical Control Makes the Difference

ARO coatings transform mechanical wear from an operational risk into a controlled variable by protecting critical areas and optimizing asset performance throughout its life cycle.
