In this experimental work, Al-Si (A356) was improved with a mixture of graphite particles and fly ash using the stirring casting technique. Dust particles from fly ash obtained from the NTR thermal power plant during use in combination with graphite particles that have self-lubricating properties. The reinforcement is mixed in various proportions with the A356 alloy with 2% by weight. % graphite and 2-4% by weight. % fly ash dust particles. After making the basic and hybrid alloy connections, wear is calculated during the dry slip test. Dry slip wear test of different loads 5N, 10N and 15N, sliding time of 15 minutes, 30 minutes and 45 minutes respectively with a disc diameter of 60 mm. To study the effect of wear parameters on friction, various techniques are used such as Taguchi and ANOVA. In addition, the smallest value was selected using the "MINITAB18" program status functions.
