· JVASP-102675· TaTiCN

TaTiCN is a refractory ceramic composite combining tantalum, titanium, carbon, and nitrogen phases, belonging to the family of high-entropy carbonitrides. This material is engineered to deliver extreme hardness and thermal stability, making it valuable for cutting tool coatings, wear-resistant surfaces, and high-temperature applications where conventional hard coatings would fail. It represents an advanced research material that extends beyond traditional PVD/CVD coatings by leveraging multi-element synergy to balance hardness, toughness, and oxidation resistance—advantages particularly significant when operating at elevated temperatures or against aggressive abrasive wear.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
