The landform obviously had controlled the covered ratio, occurrence, morphological feature of the cobaltrich crusts. The very gentle or steep slopes of seamounts are unfavourable to the growth of the cobaltrich crusts. The crusts mainly are platy on the steep slopes of seamounts, and rippled or pillow on the gentle slopes. The platy crusts mostly appear on the slopes of the seamounts, but the pebble crusts or cobaltrich nodules on the flat or low areas.

Microstructural observation revealed that a lot of epitaxial growth fibrous AlN polytype occurred in matrix. Y_2O_3 seems to act as a densifier for in-situ formation material and as medium for growth of fibrous polytype. SiO_2 is the growth promoter for fibrous polytype. The occurrence of fibrous polytype may increase the strength and toughness of AlN ceramic composite material.

实验结果表明，AlN-Y_2O_2-SiO_2系陶瓷复合材料的抗弯强度和断裂韧性较AlN陶瓷均有大幅度的提高，微观结构观察发现基体中存在大量共生的纤维状AlN多型体(27R，21R)，系统中Y_2O_3不仅是原位生长复合AlN材料的致密剂，而且是纤维状多型体生长的媒介，SiO_2，是纤维状多型体生长的助生长剂，基体内纤维状多形体的存在提高了AlN陶瓷的强度和韧性。
