The bonding strength of material interfaces for several substrate/coating (ceramic/ceramic and ceramic/metal) systems has been investigated by means of the pulsed laser induced spallation method. Test data are presented for thin coatings such as 1 to 15Ám SiC by CVD, 1 to 4Ám TiC and TiN by PVD deposited on sapphire substrates, as well as 1 to 2Ám Au, Sn and Ag deposited by sputtering on sapphire, fused quartz and glass substrates. For identically prepared specimens, the measured threshold energy levels are reproducible, thus leading to reproducible bond strength values, while the spal1 size, as expected, is dependent on the laser pulse energy level.
