Surface strengthening of single-crystal alumina by high-temperature laser shock peening

Surface strengthening of single-crystal alumina by high-temperature laser shock peening

This manuscript reports a novel process of high-temperature laser shock peening (HTLSP) for surface strengthening of single-crystal ceramics such as sapphire and reveals its fundamental mechanisms. HTLSP at 1200°C can induce a high compressive residual stress on the surface of sapphire while minimiz...
