At the same time because of the insolubility of calcium phosphate, topical extortionate concentration of calcium ions and phosphate ions, the vary of ph value and the effect of osteoblasts and proteins in oregano - bone matrix, the calcium ions and phosphate ions gave birth to crystal nucleus and came into being osteo - salt deposition, furthermore to form mineralized bone. finally, at the host osseous lamella far away the implanting area we found some material granules
藉助于掃描電鏡等測試手段,實驗發現隨著植入時間的延長,材料區域的面積不斷縮小,晶體顆粒間的頸部連接斷開,顆粒的結構和形貌發生了較大的變化,且材料的內部出現了生命元素碳和硫等。For the fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w alloy system, the peak value of quenching appears in 950 - 1100. the peak value increases with the increment of w. when the content of w is 2 %, the temperature of temper hardening is 550. for the fe - 2 % c - 4 % v - 4 % mo - 5 % cr - 2 % w alloy, the appropriate quenching temperature can be controlled in 1000 1050 and the time of preserving heat is 12min
