he metal-sprayed coating applied over steel and iron structures is a complete protective system within itself. However, sealant is used in order to enhance the protection level and give the coated metal a pleasing appearance. Among the beneficial characteristics of aluminizing are:

Advantages of Aluminizing and Spray Galvanizing in comparison to ordinary painting |
All metals have properties that cause them to react as an anode or a cathode when coupled to another material in a corrosive environment. The application of zinc / aluminum (anodic coating) to iron substrates forms a protective layer and results in corrosion protection referred to as cathodic protection or sacrificial protection.
Aluminizing or Spray Galvanizing provides good mechanical interlocking based on quality abrasive blasted pre-treatment. Coating thickness of up to 500 microns can be applied though the industry standard is 100 - 150 microns. Aluminizing process is ideal in high temperature environment to prevent oxidation and corrosion. Coating with sealant provides a base for paints for longer life to structures.
The advantages of our services can be understood by the following |
Every coating process is tested for adherence to IS & BS standards .We carry out the job of spray galvanizing / aluminizing to the coating thickness of 175 - 200 microns to be confirmed by the thickness measurement gauge before and after the coating process The brief details of the test carried out on Zinc or Aluminized coating surfaces are: THICKNESS OF COATING : This test is carried out to ensure that the coating provided is to the accepted standards. A self calibrated coating thickness gauge with test pieces is used for testing the thickness of Zinc/Aluminum Coating as per IS: 3203:1982. PURITY TEST : Purity of Zinc / Aluminum wire used is tested in an external laboratory ascertain which should 99.95% pure be as per IS: 209.A certificate to this effect can be provided to the customer along with our test certificate if desired. BOND TESTS : This test indicates the mechanical bonding of Zinc/Aluminum coating to the substrate. This is carried out by using an special Bond Tester as per ASTM-D 4541-1985. A dolly is fixed on a sample piece using an adhesive material and by forcing it to be pulled out by using the Bond Tester. The load at which this dolly gets separated from the test piece indicates the bonding strength in terms of PSI (Pound per Square Inch). Secondly by using a scriber, several lines at close intervals are drawn on the coated surface as per IS: 5905. The coating along the lines should not peel-off. |
Machining induces stresses in parts. The bigger and more complex the part, the more the stresses. These stresses can cause distortions in the part long term. If the parts are clamped in service, then cracking could occur. Also hole locations can change causing them to go out of tolerance. For these reasons, stress relieving is often necessary. Typically, the parts that benefit from stress relieving are large and complex weldments, castings with a lot of machining, parts with tight dimensional tolerances and machined parts that have had a lot of stock removal performed. Stress Relieving is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Stress relieving is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming. Stress relieving is done at about 650°C for about one hour or till the whole part reaches the temperature. This removes more than 90% of the internal stresses. Alloy steels are stress relieved at higher temperature. After removing from the furnace, the parts are air cooled in still air. Stress Relieving is often associated with increasing the strength of material, but it can also be used to alter certain manufacturability objectives such as improve machining, improve formability, restore ductility after a cold working operation. Thus it is a very enabling manufacturing process that can not only help other manufacturing process, but can also improve product performance by increasing strength or other desirable characteristics. Steels are particularly suitable for heat treatment, since they respond well to heat treatment and the commercial use of steels exceeds that of any other material. At Mythri Metallizing (P) Ltd., we are rather proud to boast that we are equipped with the state-of-the-art ,a 5x3x2.5 meters furnace for the purpose of Stress Relieving at our works in Peenya Industrial Area, Bangalore. |
