HC386T Composite Chrome Oxide Powder

Advanced Wear-Resistant Coatings for Demanding Applications

Hunter Chemical’s HC386T is a high-performance composite chrome oxide powder engineered to deliver dense, durable, and wear-resistant coatings compared to pure chrome oxide. Formed with silica and titania, HC386T is a composite chrome oxide designed for use in both plasma and combustion spray systems.

This advanced formulation makes HC386T an excellent solution for applications requiring superior wear protection due to abrasion, corrosion, or impact. HC386T supports higher deposit efficiency than pure chrome oxide and produces exceptionally smooth coatings across a range of industrial environments.

Sintered and Agglomerated for Optimal Morphology

Hunter Chemical produces HC386T using a controlled sintering and agglomeration process. This manufacturing method yields irregularly shaped particles with a mottled surface texture. This unique morphology offers several performance advantages compared to the blocky, angular shape of similar materials commonly available on the market.

The irregular particle shape improves powder flow characteristics during spraying while supporting more consistent melting behavior. This leads to a more homogeneous coating with improved bonding and reduced porosity. In practice, customers experience smoother sprayed surfaces and more reliable coating results, even on complex geometries.

Controlled Particle Size Distribution

HC386T is classified to a nominal particle size range of 15 to 60 microns. This controlled distribution enables consistent feed rates and stable deposition across a variety of thermal spray systems. The particle sizing also contributes to higher deposit efficiency compared to pure chrome oxide, helping reduce material waste and improve overall process economics. Operators benefit from improved spray stability and consistent coating thickness across production runs.

Equipment Compatibility and Coating Results

HC386T performs exceptionally well in both plasma and combustion spray systems. Its engineered morphology supports efficient heat transfer and uniform particle melting, which contributes to smoother coatings directly out of the spray process.

Compared to pure chrome oxide, parts sprayed with HC386T have harder and denser coatings, often reducing or eliminating the need for extensive post-processing. This can translate into faster production cycles and lower finishing costs, particularly in high-volume or precision-critical applications.

Applications and Target Industries

HC386T is commonly used in industries where components are exposed to severe wear conditions and require reliable surface protection, including:

Petrochemical

Protecting equipment exposed to corrosive chemicals, pressure, and high temperatures

Paper

Extending the life of components subject to abrasion and continuous operation

Textile

Improving durability of parts exposed to friction and repetitive motion

In these applications, HC386T provides a hard, dense coating that resists wear while maintaining consistent performance over time.

Typical components coated with HC386T include:

Pump Impellers | Mechanical Seals
