Application Research of Sodium Titanate and Potassium Titanate in Copper-Free and Antimony-Free NAO Friction Material
The properties of moisture,micromorphology and particle size of sodium titanate and potassium titanate were analyzed and compared.Based on SAE J2522 and SAE J2521 test standards,the frictional properties and noise of sodium titanate and potassium titanate after being applied to copper-free and antimony-free NAO friction material was analyzed and compared with LINK M3900 NVH inertia brake test bench.The results show that the nominal friction coefficient of sodium titanate sample is 10.3%higher than that of potassium titanate sample,and the minimum friction coefficient of Fade1 chapter is 25%higher than that of potassium titanate sample.The noise evaluation grade of sodium titanate sample was AAA and that of potassium titanate sample was AA.The noise performance of sodium titanate sample was better.Sodium titanate has better cost performance and can replace imported potassium titanate in the application of copper-free and antimony-free NAO friction material.
