Operating background
Protection for material-contact surfaces exposed to abrasion, erosion and repeated impact.
Solutions
Wear and Erosion Protection
Define particle size, velocity, impact angle, material path, substrate and temperature before selecting a wear-protection system.
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.
For wear or particle-erosion problems, consult the wear-protection coating family while keeping the actual wear mechanism, substrate and operating conditions central to the application review.
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

Frequently asked questions
How do I choose between wear-resistant coating systems?
Define particle type, size, velocity, impact angle, material path, substrate, temperature and corrosive exposure. These factors determine whether the dominant mechanism is abrasion, erosion, impact or a combined condition.
Can one wear coating cover every transfer point?
Not necessarily. Bends, impact zones, sliding surfaces and high-temperature areas can require different preparation, detailing or product functions.
What should be checked during application?
Check preparation, continuity, edges, welds, difficult access areas, layer records, curing and any representative trial area required by the reviewed procedure.
