Current MAO capabilities at Robust Metal include black and gray finishes, with ongoing development expanding the color palette.

Applications include pump components, valve stems, fastener systems, and sliding contact surfaces where galling resistance is critical.

PVD Coating: Multi-Dimensional Color and Texture

Physical Vapor Deposition (PVD) applies thin, dense ceramic coatings to titanium substrates in a vacuum chamber.

This process produces four versatile color options including glossy black, matte black, gold, and silver-toned finishes.

PVD gold and black finishes over textured titanium substrates create a luxurious, multi-dimensional appearance valued in luxury goods and architectural hardware.

The coating exhibits excellent adhesion, scratch resistance, and chemical stability.

PVD processing maintains dimensional accuracy, making it suitable for precision-machined components requiring tight tolerances.

Sandblasting: Uniform Matte Surfaces

Sandblasting propels abrasive media at controlled velocities to produce a uniform, non-reflective surface finish.

Particle size and blasting pressure are adjustable, enabling gloss levels from fine satin to coarse matte.

Sandblasted titanium surfaces effectively hide fingerprints, minor scratches, and handling marks, making them practical for consumer-facing products.

This treatment also prepares surfaces for subsequent coating or anodizing processes, improving adhesion and finish uniformity.

Typical applications include electronic device housings, automotive interior components, and industrial control panels.

Stone Washing: Vintage Texture for EDC and Jewelry

Stone washing, frequently termed "vintage finishing," imparts a subtle, worn-in texture to titanium surfaces.

This mechanical tumbling process with abrasive stones creates micro-craters and soft edge rounding.

The resulting finish carries a distinct character valued in everyday carry tools, watch components, jewelry, and decorative accessories.

Each stone-washed piece exhibits unique surface variation, ensuring no two components share identical appearance.

Water Grinding: Precision Polishing for Secondary Processing

Water grinding employs precise abrasive belts with water cooling to achieve smooth, consistent surfaces with soft luster.

This process removes machining marks and surface defects while maintaining flatness on panels and sheet components.

Water grinding serves as an ideal pre-treatment before anodizing, PVD coating, or painting, ensuring optimal substrate condition for subsequent finishing layers.

Brushing: Linear Texture for Modern Aesthetics

Brushing produces linear, unidirectional textures across titanium surfaces using abrasive belts or wheels.

Brushing depth is adjustable, allowing fine satin lines to coarse architectural textures.

Brushed titanium appears extensively in consumer electronics, architectural cladding, and luxury product packaging.

The directional grain pattern creates subtle light reflection that emphasizes form and geometry without harsh glare.

Etching and Nitriding: Cookware Performance Enhancement

This specialized treatment combination is engineered specifically for titanium cookware, particularly woks and frying pans.

Etching creates a micro-textured surface that improves oil retention and food release properties.

Nitriding follows to boost surface hardness and create a durable, non-stick cooking surface.

The resulting finish is safe for high-temperature cooking, scratch-resistant, and free from potentially harmful coatings.

Polishing and Mirror Polishing: Ultra-Reflective Finishes

Polishing transforms titanium surfaces from standard mill-finish to bright, reflective condition.

Mirror polishing achieves exceptional reflectivity through progressive abrasive refinement and buffing compounds.
