Latest Patents

One of Nozaki's latest patents is a method for improving the durability of exhaust pipes. This invention focuses on an exhaust gas purification apparatus that utilizes ammonia generated from a urea aqueous solution. By applying a shot peening treatment to the welded portion of the exhaust pipe made from ferritic stainless steel, the tensile residual stress is transformed into compressive residual stress. This process also reduces the diameter of metal crystal grains, ultimately enhancing the durability of the exhaust pipe.

Another significant patent by Nozaki is a method for improving the fatigue strength of cast iron materials. This invention aims to elevate the fatigue strength of spherical graphite cast iron to match that of carbon steel subjected to carburizing and quenching. The method involves multiple shot peenings using specific shot diameters on spherical graphite cast iron that has undergone quenching and tempering heat treatment. The resulting material composition includes precise percentages of carbon, silicon, manganese, phosphorus, sulfur, magnesium, and copper.
