Titanium Aluminium Nitride

SMT   PVT LTD’s TILUM-n is a Special application pharma grade coating which provides superb wear resistant, corrosion resistant and anti-sticking properties deposited at high temperatures. It is titanium aluminium nitride based alloy coating deposited by the State-of-the-art physical vapour deposition (PVD) process.   

SMTPL’s TILUM-n has exceptional performance due to its hard and dense coating structure which keeps the coating intact even at severe wear conditions. The dense coating structure blocks the pinholes and thus enhances the corrosion resistance property. The pre-coating in situ plasma cleaning treatment before coating process and coating species diffusion onto the tool surface, augment the coating adhesion with the tool and intactness of coating while tablet compression at very high loads. The surface energy of the coating is very low which inhibit reaction with aggressive formulation. TILUM-n coating exhibit no cracks even at high loads even after prolonged usage resulting in enhancing production efficiency. Tools tempered above 4500C are recommended for this coating. TILUM-n coating can be deposited on punches to deal with hard abrasive Ayurvedic and Herbal formulations used for tablet compression. The coating thickness is kept around 2 microns and can be modified as per application.
