Haygor Advanced Coating Service
AlTiNAluminum Titanium Nitride
Hold the surface together when heat, oxidation and abrasive wear converge.
Haygor’s application-first review begins with the failure mode, the operating environment and the part—not a coating acronym alone.
Coating overview
High-temperature wear protection for hard-working surfaces.
AlTiN is a hard ceramic nitride coating often evaluated for components and tools that face elevated temperature, oxidation, abrasion or particle erosion. Its strongest value is not simply greater hardness; it is the ability to retain useful surface protection when heat begins to overwhelm a general-purpose wear coating.
For Haygor applications, AlTiN may be considered where a thin engineered surface is preferred over changing the entire component material. Final suitability depends on the substrate, heat treatment, service temperature, geometry, loading and required dimensional control.
Problems it helps solve
Start with what the surface is doing wrong.
AlTiN becomes relevant only when its strengths align with the observed failure, the component and the operating conditions.
Hot wear and edge breakdown
Cutting edges and loaded surfaces can soften, round over or lose geometry as temperature rises.
Oxidation-driven surface loss
Repeated heat cycles can accelerate scale formation and expose the underlying substrate.
Hard-particle erosion
Entrained particles or high-velocity contact can progressively remove an unprotected surface.
Short life in dry service
Reduced lubrication concentrates frictional heat and can make a conventional wear coating fail earlier.
Why use an advanced coating
Engineer the working surface—not just the bulk material.
Compared with an uncoated component or a general-purpose treatment that is not matched to this failure mode, AlTiN provides a more targeted surface strategy.
Performance targeted to heat
A stronger starting point than an uncoated surface or a general-purpose coating selected only for room-temperature wear.
Wear protection at the surface
Adds a hard engineered barrier without replacing the bulk material of the part.
Oxidation-focused chemistry
Often preferred when thermal stability and oxidation resistance matter more than color or basic abrasion resistance.
Precision-friendly approach
A thin coating can preserve functional geometry when thickness, masking and finishing are reviewed in advance.
Industries & common uses
Where AlTiN is commonly evaluated.
These are application starting points—not blanket approvals. Substrate, geometry, process conditions and qualification requirements still control the final recommendation.
Cutting tools
End mills, drills, inserts, taps and other tools exposed to concentrated heat and abrasion.
Aerospace & power components
Compressor-related parts, turbine-adjacent hardware and erosion-prone components subject to qualification.
Turbocharger & engine hardware
Hot-running rings, valves and rotating components where heat and wear interact.
Dies & forming tools
High-load tooling where thermal cycling and surface wear limit consistency.
Process instrumentation
Selected diaphragms and exposed surfaces in hot abrasive service after application review.
Precision mechanical components
Finished parts requiring surface protection without major dimensional build-up.
Selection guidance
Know when AlTiN is a strong candidate—and when to pause.
The right coating discussion helps narrow the options without presenting any coating as a universal answer.
Strong-fit signals
- Heat is a primary driver of wear
- Oxidation appears with repeated thermal cycling
- Abrasive particles or erosion are present
- Critical geometry must be retained
Review carefully when…
- Low-temperature friction may be the real problem
- The substrate cannot tolerate the coating process
- Deep bores or shadowed features require coverage
- A universal corrosion barrier is being assumed
Haygor application review
Four inputs move the discussion forward.
Define the failure
Describe wear, friction, corrosion, heat, sticking, galling, erosion, buildup or dimensional loss.
Document the service
Provide media, temperature, pressure, motion, load, lubrication and cleaning conditions.
Identify the component
Share the material, heat treatment, finish, geometry, drawing and critical dimensions.
Confirm qualification
Align on masking, coverage, inspection, testing, documentation, quantity and schedule.
Technical questions
Important limits to address before quoting.
Final properties and process limits must be tied to Haygor’s approved coating recipe and the exact customer component.
Will AlTiN change the part dimensions?
Advanced coatings may be thin, but even a small layer matters on tight fits, threads, bores, sealing surfaces and sharp edges. Critical dimensions should be identified for masking, tolerance review or post-coating finishing.
Can every internal bore, recess or thread be coated?
Vacuum and deposition processes are strongly influenced by the selected process, line of sight, fixturing and geometry. Deep bores, hidden features and shadowed surfaces may receive limited coverage. Haygor should review the drawing before coverage is promised.
Is AlTiN guaranteed to extend service life?
No coating should be presented as a universal service-life guarantee. Improvement depends on whether the coating is matched to the substrate, dominant failure mode, operating environment, preparation, thickness, finish and inspection criteria.
Talk with Haygor
Bring the component—and the performance problem.
Send the material, drawing, operating conditions and current failure mode. Haygor can determine whether AlTiN is a credible candidate or whether another surface strategy should be evaluated.
