High Performance Aluminum Titanium Coatings for Anti-Slip Applications

This paper presents the development of a solid homogeneous Aluminum Titanium Alloy wire which can produce, using conventional twin wire arc spray systems, a Thermal Sprayed Anti-Slip coating that will be effective in a range of applications and environments.  In addition to its anti-slip characteristic the coating will also provide a hard wearing coated surface that provides corrosion protection to steel substrates.  It will be shown that the macroscopically textured coating is extremely resistant to wear and maintains its anti-slip performance for a relatively long period even in high pedestrian traffic areas as assessed using the BS7976-2 2002 Pendulum Test method.  Vehicle traffic applications will also be discussed.  This paper will also demonstrate that the Aluminum Titanium Alloy has the same corrosion resistance as pure aluminum due to hard intermetallic particles within the alloy being chemically inert allowing this coating to be confidently used in environments in which TSA (Thermal Sprayed Aluminum) coatings are traditionally specified and used.  Additionally the properties of the coatings are presented and compared to the wire feedstock to confirm the sprayed layer retains the required elements and all areas are equally durable.
