PVD coatings are generally safe, both for the environment and for human health, once they have been applied.
They are also considered food-safe and are widely used in various industries due to their durability and resistance to wear and corrosion.
5 Key Points You Need to Know
1. Environmental Safety
PVD processes are environmentally friendly compared to traditional "wet" plating techniques.
They significantly reduce the use of toxic substances and the need for their management and disposal.
The process does not release harmful gases or produce water wastes, making it a cleaner alternative.
Additionally, PVD coatings are recyclable, which helps preserve the value of the base material, such as stainless steel.
2. Health Safety
While PVD coatings are made up of small particles, they pose no health risk once applied.
During the application process, precautions should be taken to avoid inhalation of the particles, which can cause health problems if lodged in the lungs.
However, once the coating is applied, the particles are firmly bonded together and do not become airborne, eliminating the risk of inhalation.
The coatings are applied in very thin layers, further reducing any potential health hazards.
3. Food Safety
Most PVD finishes are food-safe.
They adhere strongly to their substrate and are often chemically and biologically inert, making them suitable for use in the cutlery industry and commercial kitchen equipment.
The wear-resistant properties of PVD coatings ensure they can withstand significant wear and tear without compromising their safety.
4. Applications and Durability
PVD coatings are versatile and used across various industries due to their ability to provide durable, wear-resistant, and corrosion-resistant finishes.
They are commonly used in decorative applications, such as watches and household items, where they offer resistance to scratches and tarnishing.
The coatings, such as titanium nitride, are known for their superior hardness and durability, making them ideal for tools and fixtures that require long-lasting performance.
5. Summary
In summary, PVD coatings are safe for use in various applications once applied, offering environmental benefits, health safety, and food safety.
They are a preferred choice in many industries due to their durability and resistance to wear and corrosion.
