Thermal Spray

As a professional high‑performance industrial roller manufacturer, AstraRoll specializes in custom‑engineered thermal spray coated rollers and high‑performance thermal spray rollers, applying advanced thermal spray technologies including HVOF (High‑Velocity Oxygen Fuel), plasma spraying, arc spraying and flame spraying. These premium‑grade coatings deliver exceptional wear resistance, corrosion resistance, high‑temperature stability, electrical insulation and low‑friction properties, drastically extending roller service life in heavy‑abrasion, high‑temperature, acid‑alkali and harsh industrial environments. Widely used in metal processing, mining, new energy, packaging, textile, chemical and paper industries, thermal spray coated rollers solve core equipment pain points of rapid wear, surface corrosion and coating peeling.

Unlike conventional electroplating, painting or rubber coatings, thermal spray coatings feature dense layered structures, ultra‑high hardness and strong substrate bonding. We select high‑strength carbon steel, alloy steel, stainless steel and aluminum alloy roller blanks, then apply customizable coating materials including tungsten carbide, chromium oxide, aluminum oxide, ceramic composites, nickel‑based alloys and self‑lubricating composite materials. We precisely control coating thickness, porosity, bonding strength and surface roughness, with post‑coating precision grinding and polishing available to meet strict precision requirements for high‑speed industrial production lines.

Core Product Range

HVOF High‑Velocity Thermal Spray Hard Coated Rollers
Ultra‑dense tungsten carbide HVOF coatings with superior hardness and wear resistance, ideal for mining conveying, metal rolling, heavy‑duty calendaring and high‑abrasion continuous‑production rollers.

Plasma Thermal Spray Ceramic Coated Rollers
Chromium oxide and aluminum oxide ceramic thermal spray coatings, featuring insulation, anti‑corrosion and high‑temperature resistance. Perfect for electronics industry, clean‑room precision processing and textile heat‑setting rollers.

Arc‑Sprayed Alloy Anti‑Corrosion Thermal Spray Rollers
Nickel‑based alloy and zinc‑aluminum thermal spray coatings, excellent acid‑alkali resistance and waterproof performance. Suitable for chemical industry, fertilizer processing and humid outdoor logistics conveying rollers.

High‑Temperature Resistant Thermal Spray Heat‑Treatment Rollers
Heat‑stable composite thermal spray coatings resisting thermal oxidation and thermal shock, designed for heat‑transfer rollers, baking line rollers and thermal‑pressing equipment rollers.

Self‑Lubricating & Anti‑Stick Thermal Spray Coated Precision Rollers
Custom self‑lubricating composite thermal spray coatings with low friction and non‑stick properties, used for flexible packaging, film converting and ultra‑thin‑film processing precision rollers.

Key Features & Product Advantages

Superior Wear‑Resistant & High‑Hardness Performance
Thermal spray coatings achieve far higher surface hardness than hard chrome plating and ordinary heat‑treated steel, effectively resisting long‑term friction, scratching and sharp‑particle abrasion.

Excellent Multi‑Environment Adaptability
Customizable coatings withstand high temperatures, strong acids, alkalis, solvents, moisture and dust, stably operating in mining, chemical, high‑temperature thermal‑processing and clean‑room scenarios.

Strong Coating Bonding & Low Porosity
Advanced thermal spray processes ensure tight coating‑substrate adhesion with low internal porosity, avoiding peeling, cracking or spalling under heavy loads, impact and thermal cycling.

Multifunctional Customizable Performance
Coatings can be tailored for wear resistance, anti‑corrosion, high‑temperature resistance, insulation, anti‑static and low‑friction functions, matching diversified industrial process requirements.

High‑Precision Surface Consistency
Post‑coating precision grinding maintains strict roundness, straightness and concentricity, supporting stable high‑speed rotation and consistent processing quality for precision production lines.

Significant Cost‑Saving Benefits
Long‑lasting thermal spray coatings greatly reduce roller replacement frequency and production downtime, lowering long‑term maintenance and operating costs for enterprises.
