Wetting of AlN and TiC by Liquid Ag and Liquid Cu

摘要: The wetting of AlN and TiC by liquid Ag Cu was investigated the sessile drop technique at 10−6 torr or less. An empirical relation established between cosine contact angle temperature surface tension drop. critical for spreading its physical significance are discussed. A method estimating energies ceramics is proposed. estimated to be 1242±158 dynes/cm that 990±110 dynes/cm. followed equation γLv (Ag) (dynes/cm) = 1092–0.14T (°C) γLV (Cu) 1462–0.27T (°C).
