WP10. Revestimentos autoadaptativos, sensoriais e multifuncionais
PPS6
GOLDCUT (TiNAg) | MAXCUT (TiAlY)
Better surface finish quality and longer tool durability
DESCRIPTION
Multifunctional PVD coating family for chip-removal cutting tools, formulated to operate under conditions where conventional coatings (TiN, TiAlN) reach their performance limits. They combine high hardness and thermal stability with self-adaptive mechanisms activated by the operation itself, which help reduce friction and cutting forces. revestimentos convencionais (TiN, TiAlN) atingem os seus limites de desempenho. Combinam dureza elevada e estabilidade térmica com mecanismos auto-adaptativos ativados pela própria operação.
TiNAg — a difusão controlada de Ag para a superfície do revestimento, induzida pela temperatura de contacto, forma uma película tribológica auto-lubrificante que reduz o coeficiente de atrito e mitiga a aderência da apara.
TiAlYN — a incorporação de Y promove a formação de uma camada protetora de óxidos termodinamicamente estável, com elevada resistência à oxidação acima dos 800 °C.

MAIN APPLICATIONS
- • Dry machining or minimum quantity lubrication (MQL)
- • Machining of hardened steels, Ni/Co superalloys and Ti alloys
- • High-speed milling, turning and drilling operations
- • Replacement of TiN/TiAlN coatings in applications where the cutting temperature exceeds 700 °C

C-GLIDE (DLC) | MAXGLIDE (WSC)
Greater efficiency in plastic injection and mechanical forming processes
DESCRIPTION
Low-friction PVD coatings with self-adaptive behavior, optimized for tribological applications under harsh conditions:
A Diamond-Like Carbon (DLC) variant with high adhesion to the substrate, thermal stability superior to that of conventional DLC (500 °C), and a very low coefficient of friction (μ < 0.1) under dry sliding conditions.
WSC — a tungsten disulfide-based coating with added carbon, which ensures solid lubrication and low friction (μ ≈ 0.05–0.15) even under high loads.
Variante de Diamond-Like Carbon (DLC), com elevada adesão ao substrato, estabilidade térmica superior a um DLC convencional (500 °C) e coeficiente de atrito muito reduzido (μ < 0,1) em deslizamento seco.
WSC — revestimento à base de dissulfureto de tungsténio com adição de carbono, que assegura lubrificação sólida e baixo atrito (μ ≈ 0,05–0,15) mesmo sob cargas elevadas.
MAIN APPLICATIONS
- • Stamping and forming tools for high-strength steels and aluminum alloys
- • Injection mold components for glass-fiber reinforced or abrasive-filled plastics
- • Machining of light alloys (Al, Mg) prone to chip adhesion
- • Mechanical components subject to dry sliding (seals, pistons, etc.)
- • Replacement of conventional coatings in applications where adhesion (galling), engripamento or premature wear is observed
SENSOPRESS (CrN)
In-situ pressure variation monitoring for tools and components
DESCRIPTION
Functional PVD coating that integrates a a CrN-based sensing with piezoresistive response com resposta piezoresistiva, permitindo a medição for tools e em tempo real da pressão de contacto na interface ferramenta-peça.
Additionally, the sensing layer exhibits a measurable thermoresistive response, enabling simultaneous acquisition of pressure and contact temperature from a single coating architecture. Direct integration into the component, without the need for discrete external sensors, brings sensing closer to the actual load zone, with high spatial resolution and minimal mechanical interference in the process.
MAIN APPLICATIONS
- • Forming processes
- • Plastic injection
- • Support for process digitalization and Industry 4.0 strategies
- • Other applications where real-time mapping of contact pressure distribution is critical for process optimization, anomaly detection and predictive maintenance
SENSOCUT (TiAlN)
In-situ temperature variation monitoring for cutting tools
DESCRIPTION
Multifunctional coating based on a multilayer architecture that combines tribological protection with in-situ temperature monitoring capability. The TiAlN layer provides high hardness and excellent oxidation resistance in demanding cutting operations, with stable tribological behavior at elevated temperatures. The integrated thermoresistive layer within the architecture enables temperature acquisition in the operating zone based on changes in electrical resistance, maintaining signal integrity even under high mechanical and thermal loads.
MAIN APPLICATIONS
- • Turning operations with difficult materials (superalloys, hardened steels, titanium alloys)
- • Support for predictive maintenance strategies and real-time optimization of cutting parameters
ADVANTAGES
Reduction of friction
Improved wear and oxidation resistance
Corrosion prevention
Non-stick coatings for smart production with pressure and temperature sensors
