What Is a Plasma Spray Electrode?
A plasma spray electrode is a tungsten-based consumable used in thermal plasma spray systems to generate a stable, high-temperature plasma arc. It enables metal or ceramic powders to melt and accelerate toward the substrate, forming durable protective coatings in aerospace, medical, and industrial applications.

Why Plasma Spray Electrode Quality Matters
In plasma thermal spraying, the electrode is one of the most stressed consumable components. Poor electrode quality often leads to unstable arc ignition, rapid erosion, frequent replacement, coating inconsistency, and unplanned downtime.
Our Engineering Solution
We use rare-earth tungsten tips (Ce-W, La-W, Th-W) combined with a copper alloy rod, bonded into a single integrated structure using vacuum NDB (Non-Defective Bonding).
This design ensures excellent heat transfer, fast heat dissipation, stable arc behavior, and controlled wear — significantly extending electrode service life under extreme plasma spray conditions.

Key Features & Operator Benefits
Arc-Erosion Resistance
Optimized tungsten–copper structure resists arc erosion under continuous high-temperature plasma spraying, delivering longer service life and fewer changeovers.
Easy Arc Ignition
Rare-earth tungsten tips provide excellent electron emission, enabling fast ignition, lower start-up voltage, and stable plasma formation.
High Quality Control
Strict raw material inspection, controlled bonding process, and final dimensional and performance checks ensure batch-to-batch consistency.
Smooth & Predictable Operation
Stable arc behavior and predictable wear patterns make daily operation easier for technicians, reducing interruptions and production stress.
Designed for Extreme Plasma Spray Conditions
Our tungsten-copper plasma spray electrodes withstand operating environments exceeding 10,000 °C, while enduring severe thermal shock and mechanical stress during continuous spraying.
This ensures complete melting of metal or ceramic powders, high-velocity particle acceleration, and uniform, high-quality coating deposition.
