Abstract:  
When you use compressed air to fire millions of tiny BBs at engine parts, it makes the metal more durable for years to come. It’s not really visible, but at 10-times magnification, the metal is dimpled all over. “The benefit is really below the surface,” said Walter Beach, vice president of Peening Technologies, a small service company founded by his father in 1966. “What you don’t see.” The same could be said for Peening Technologies, which is in an unassuming brick building on a dead-end street in East Hartford. Inside, the noise is relentless as giant automated machines hurl those balls no bigger than 33/1000th of a inch.
