Benefits of Black Coated Instruments

 Benefits of black coated surgical instruments

Black coated surgical instruments are not only visually more attractive than the stainless-steel ones, there are several other benefits as provided below:

-        Non reflective surface reduces eye-fatigue  

-        Has prolonged life

-        Up to 10 times harder than stainless steel

-        60% lower wear rate than stainless steel

-        Corrosion resistant due to oxidized aluminum coating

-        Anti-allergic due to the absence of Chromium and Nickel coating 

-        Easy to clean

Making of the black coating instruments

The black coatings are created by applying a layer of Titanium Aluminum Nitrate (TiAIN) to the instrument, using an environmentally friendly Physical Vapor Deposition (PVD) process.

In this process Titanium and Aluminum are magnetron-sputtered onto the substrate in a vacuum chamber. The metal particles of the target are transformed into vapor phase, they interact with Nitrogen ions and get deposited onto the instrument as a few microns (µm) thin, high-density layer.

Oxidized Aluminum (Al2O3) at the surface of the coating acts as a corrosion barrier that has been proved by electro-chemical tests.

Moreover, the coating also provides a hydrophobic effect, lowered surface tension of the surface layer makes the instruments easier to clean.

Chromium and Nickel compounds are absent from the surface layer making the coating biocompatible.

Coating can be applied on all types of surgical instruments including:

Surgical Instrument Care and Handling

RINSING Immediately after use, rinse surgical and dental instruments under warm or cool running water to remove all blood, body fluids and tissue. Dried soils may damage the surgical and dental instrument surface and make cleaning very difficult. Do not use hot water as this will coagulate proteinous substances. CLEANING TECHNIQUES Time, temperature, and agitation play important roles in the cleaning process. Time  — the efficiency of cleaning chemicals is often time dependant Temperature  — higher temperature cleaning solutions result in better cleaning Agitation  — whether manual or ultrasonic, it is helpful in loosening the soil on the surface of the instrument Automatic Washer Sterilizers Follow manufacturer’s recommendations. Lubricate surgical and dental instruments after last rinse cycle and before sterilization cycle. Manual Cleaning 1. Use stiff plastic cleaning brushes. Do not use steel wool or wire brushes. 2. Use only neutral pH detergents. If not rinsed properly, low pH

Which Alloy is Best for My Surgical Instruments?

  Stainless Steel (Inox) Our standard line of instruments is manufactured of highest quality materials. They are made of austenitic 316 steel commonly known as “surgical steel” or “marine grade steel.” Stainless steel, also known as Inox (from the French word "inoxydable"), is highly corrosion resistant and it is a common choice of material for biomedical implants or body piercing jewelry. It is in compliance with ASTM F138. This WPI line is an excellent alternative to German surgical instruments . The high-quality, corrosion-resistant instruments are available at a fraction of the price of German surgical instruments , which are also manufactured from the same type of steel. Stainless steel is well suited for medical purposes, because this stainless steel, magnetic alloy has excellent corrosion resistance and good salt resistance. Temperature resistant up to 400°C, it can be autoclaved at 180°C. Almost as strong as carbon steel, Inox is an excellent general-purpose alloy fo
