Use steel rings and keep up on your chain cleaning. It may be that the type of lube you are using is attracting grit and or the frequency of cleaning is not often enough. I just replaced my chain and rear cassette after an estimated 5000 miles. I switched back to a seven speed cassette and the corresponding chain plus I now use steel rings. My cassette was not that worn and was a bargin "performance" brand 8 speed but I wanted to change to a seven. I may go back to freewheels and a Phil hub but that's another story. Some Aluminum is tougher... 6061 being softer than 7075 but its still aluminum and road grit grinds them into chain ring guards.
