Rahul Verma is a Manager – Sales & Operations at Infinita Lab, Rahul Verma holds an undergraduate degree in Mechanical Engineering and a Master’s in Materials Science and Engineering from IIT Patna, with a specialization in thermal spray coatings to enhance the mechanical and tribological performance of marine vehicles. Thermal spray is a deceptively rich area — the right combination of feedstock chemistry, deposition method, process parameters, and post-processing can take a base substrate that would corrode in a marine environment within months and extend its service life by an order of magnitude. The wrong combination produces porosity, residual stress, and adhesion failure that is worse than no coating at all. That hands-on materials-development experience is the foundation Rahul brings to his customer work at Infinita Lab.... Read More
