Wear on the engine components has become a problem noted by many people due to its economical impact if not handled properly, such as the increase in fuel consumption and operational costs for the replacement of engine components. Usage of oil becomes a solution that is commonly used because oil can perfectly separate between two surfaces of engine components in contact so that the wear can be avoided. However, oil can not be used under certain conditions, such as extreme temperatures, corrosive environment, and nuclear radiation. One of the solutions that can be offered for this problem is the use of wear resistant coatings. <br /> <br /> <br /> <br /> <br /> <br /> <br /> In this study, the coating material is made of CuO and SnO2 nanoparticles because the materials have good wear resistant performance and good temperature stability. Both of these materials will be used in the form of thin film coated on a metal substrate by dip coating method modified using a surfactant. Both of these nanoparticles were synthesized using sol-gel method by dissolving the metal salt in the water and then adding a base to achieve a pH where there is an equilibrium between deposition and solution. The surfactant used is 1% chitosan solution. Both nanoparticle solution is then mixed in a mole ratio of CuO variations and different SnO2, which is 3: 1, 1: 1, and 1: 3. <br /> <br /> <br /> <br /> <br /> <br /> <br /> Based on the SEM images, it can be seen that the mole ratio has an effect on the results of the second thin film coating material. The more the content of CuO in the coating solution, the coating characteristics become better.
