Wear & Erosion Protection

Solutions

Wear & Erosion Protection

Protection for material-contact surfaces exposed to abrasion, erosion and repeated impact.

Operating background

Protection for material-contact surfaces exposed to abrasion, erosion and repeated impact.

Why the problem develops

Particle size, velocity, impact angle and flow concentration remove material unevenly, while moisture can add corrosion.

Application conditions

Industries
Cement · Mining & Bulk Materials · Power & Energy · Steel
Equipment
Silo and hopper · Bucket elevator · Dust collection equipment · Scrubber · Chimney and flue
Main exposure
Abrasive particles, bulk solids, dust and possible moisture
Temperature characteristic
Confirm actual continuous and transient temperature
Operating mode
Continuous or intermittent material flow with local impact zones
Primary failure mode
Abrasion, particle erosion, impact and combined corrosion
Application challenge
Access to bends, transfer points, welds and shadow zones

Common signs

Abrasion, particle erosion, impact and combined corrosion

Particle size, velocity, impact angle and flow concentration remove material unevenly, while moisture can add corrosion.

Protection objectives

  • Reduce direct substrate loss
  • Protect high-risk impact zones
  • Make inspection and local repair practical

Recommended coating system

Protection for material-contact surfaces exposed to abrasion, erosion and repeated impact.

Solution design principles

  • Confirm substrate, medium, temperature and failure mechanism before selecting a system.
  • Treat edges, welds, joints, supports and inaccessible zones as separate design details.
  • Define inspection, repair access and return-to-service requirements with the application plan.

Surface preparation

  • Record contamination, corrosion, defects, old coating and access before cleaning.
  • Remove oil, dust and unsound material; prepare cleanliness and profile to the reviewed procedure.
  • Verify retained coating compatibility and use a representative trial area when the existing system is uncertain.

Key quality controls

  • Record preparation condition and environmental readings.
  • Inspect continuity at edges, welds, joints and shadow zones.
  • Keep batch, layer, curing and inspection records traceable.

Common mistakes

  • Selecting by product name before confirming the failure mechanism.
  • Overcoating contamination, moisture or weak existing layers.
  • Ignoring details, curing conditions or the maintenance window.

Inspection, maintenance and repair

  • Inspect representative high-risk zones on a defined schedule and compare like-for-like records.
  • Repair local defects only after removing the cause and defining sound boundaries.
  • Escalate widespread cracking, leakage or substrate loss for engineering review.

Application workflow

Understand equipment and service

Record the equipment, substrate, medium, temperature pattern and access window.

Identify the failure mechanism

Separate corrosion, wear, heat flow and application causes before selection.

Define protection objectives

Define the required protection, inspection access and maintenance outcome.

Match the coating system

Match compatible layers to the confirmed substrate and operating exposure.

Control application and maintenance

Plan preparation, application controls, curing, inspection and later repair.

Suitable scope

Prepared material-contact surfaces where the wear mechanism is identified

Use limitations

Selection requires particle, impact, temperature and chemical information

Frequently asked questions

How do I know whether this solution is suitable?

Protection for material-contact surfaces exposed to abrasion, erosion and repeated impact.

What operating information should I provide?

Provide equipment, substrate, medium, concentration where relevant, continuous and transient temperature, operating cycle, visible damage, old coating and access window.

Must the old coating be removed completely?

Only unsound or incompatible layers must be removed, but retention requires adhesion, compatibility and a representative trial-area review.

What limits application conditions?

Substrate temperature, moisture, dew point, ventilation, contamination and the documented curing window must satisfy the reviewed product procedure.

How should quality be checked?

Check preparation records, continuity, difficult details, documented layer controls, curing and visible defects using traceable records.

How is later maintenance planned?

Inspect representative risk zones, correct the root cause and repair within sound boundaries using a compatible system.
