Dec 04, 2006 · However, the metal coating at the end of the metal coated fibre needs to be etched off, in order to enable splicing. After splicing the bare fibre part containing the Bragg grating, it needs to be nickel coated in a manner allowing the nickel coating to overlap the metal coating on the commercial fibre by a few centimetres. 2.1.2. Reagents
Coatings Free Full-Text Corrosion Behavior Evaluation Coatings, either soft or hard, are commonly used to protect steel against corrosion for longer service life. With coatings, assessing the corrosion behavior and status of the substrate is challenging without destructive analysis. In this paper, fiber Bragg (FBG) grating sensors were proposed to nondestructively evaluate the corrosion behavior of steel coated with two popular coatings

Effect of laser shot peening without coating on the Dec 01, 2012 · Laser peening without coating studies on 316L steel demonstrated that the state of surface stress improved from 12 MPa to a maximum of 273 MPa. The microhardness investigation confirmed LPwC resulted in work hardening and the depth profile of hardness showed that the depth of hardened layer increased with increase in laser pulse density.
Fabrication and characterization of a metal-packaged Jan 20, 2014 · Metal-packaged RFBG strain sensors can be successfully fabricated by combining magnetron sputtering and electroplating, without visible perturbation across the shape of the reflection spectrum and any discontinuity in the bonded interface between the optical fiber and the titanium layer, as well as the nickel layer and the P91 steel substrate.
Serrated grating is available with most standard load bearing bars (aluminium and steel only). The serrations are formed by placing a series of notches along the upper edge of the load bar, thus enhancing the non-slip characteristics of the grating.
Heavy Duty Welded and Riveted Steel GratingHeavy Duty Welded and Riveted Steel Grating in Stainless Steel, Aluminum and Carbon Steel . Riveted grating combines bearing bars and crimp bars by clamping them with a heavy-duty rivet - creating a high strength joint. Riveted Grating is the oldest style of grating made today. It is the most rugged and reliable, as it is based on the truss

The hot dipped zinc coating gives the product excellent anti-corrosion. Steel grating 1)Raw material :Low carbon steel, stainless steel, aluminum alloy 2)Types of Steel Grating:Plain/smooth type, I type ,Serrated/teeth type. 3)Cross bars shape:square bars, twisted square bars,round bars
SERVICE CHANNEL Industry & exhibition20 mm x 20 mm angle housing and inlaying grating; extremely stable connection between steel angle housing and concrete channel body; 10 fixing points for gratings per metre (incl. 2 times with optional locking handle) extra protection against lateral movement 90 % time savings in fixing the grating with SIDE-LOCK (compared to a conventional fixing)
Serrated grating - Weland ABH9-T is our most common variant of serrated grating and it is manufactured from pressure welded grating. Load bearing bar heights are manufactured from 25 - 35 mm as standard. H9-T is also manufactured in other load bearing bar heights and is a non-stock item.
Carbon steel bar grating and alloy steel bar grating, consisting of load-bearing pieces and cross pieces, produced as standard grating or heavy-duty grating, in panel form, whether galvanized, painted, coated, clad or plated, originating in/or exported from the People's Republic of China.
Superhydrophobic TiO2Polymer Nanocomposite Surface The surface exhibits excellent superhydrophobic properties immediately after lamination without any chemical surface modification to the TiO2 nanoparticles. Exposure to UV light causes the surface to become hydrophilic. This change in wettability can be reversed by heating the surface to restore superhydrophobicity.
Surface Area Calculation Tool - Caswell IncTo effectively work out a complex surface area, as shown left. Simply place an imaginary grid of 1 squares over the part, and count the whole squares. Then go around the perimeter and add up all the squares that are more than ½ full. Divide the total by 2 and
Aug 21, 2012 · Applying a slip resistant surface to the grating can help increase safety as well. Slip resistant surfaces that retain traction in water or snow can provide a safe walking surface in any type of environment. Plasma spray metal coatings are bonded to the surface, eliminating the risk of
