    1. 225. STRESS CORROSION CRACKING OF HOT FORMING STEELS
      Dr Carsten Lachmann (Volkswagen Aktiengesellschaft)

      Automobile Application - Forming, Joining, Painting and Final Properties
      Oral Presentation

      Stress corrosion cracking (SCC) of uncoated and AlSi-coated hot forming steel grades of 1500 and 1900 MPa tensile strength is investigated under different corrosive conditions using the VDA 238-201 step load test and the VDA 238-202 constant load test. Hydrogen charging was realized by cathodic polarization with an attached zinc coated sheet or by acid solutions.
      The 1900 MPa grades show a...

      Automobile Application - Forming, Joining, Painting and Final Properties
      Oral Presentation

      In order to meet the increasing demand for a flawless and attractively painted car, surface topography of sheet metal is becoming more and more into focus of optimization. Besides inhomogeneous painting, disturbing surface texture with long wavelength proportions can make the appearance of a coating disturbed and inferior. In order to measure and display these inhomogeneity’s, new...

    4. 90. THE EFFECT OF BONDING STATE BETWEEN THE GALVANIZED STEEL SHEETS AND THE ADHESIVE ON DETERIORATION BEHAVIOR OF ADHESIVE JOINT
      Masumi Koori (Nipponsteel)
      21/06/2021, 15:00
      Automobile Application - Forming, Joining, Painting and Final Properties
      Oral Presentation
      In the automotive industry, the needs of adhesive bonding are increasing. It is well known that the deterioration over time of adhesive joined parts is one of the problems. Therefore, we investigated the deterioration behavior of adhesive joined parts using various steel sheets. As a result, deterioration over time was caused by the becoming weaker in interfacial adhesion strength between the...

    5. 220. AN INNOVATIVE GI WITH IMPROVED GALLING AND SURFACE PROPERTIES FOR EXPOSED AUTOMOTIVE APPLICATIONS
      Bart van Veldhuizen (Tata Steel Europe)

      Zinc-Aluminum-Magnesium Coatings for Automotive Application
      Oral Presentation

      The prevention of intermetallic dross particles like Fe2Al5 in strip galvanising is paramount in making good quality exposed automotive panels. These intermetallic dross particles can create small surface features which can adversely affect the final painting quality. The formation of intermetallic dross seems inevitable during the galvanising of steel as aluminium additions are necessary to...
