  涂层开裂
     Because adding 9.0%CeO 2 results in the formation of the net shaped microcracks that are well distributed in the coating, the stress in the coating is decreased and the critical temperature of the coating fracture initiation is increased. So, the thermal resistance of ZrO 2+ 9.0%CeO 2 coating reaches the maximum value.
     ZrO2 +9.0 %CeO2 涂层在热循环中形成网状微裂纹 ,不仅可以降低涂层中的应力 ,而且可以提高涂层开裂的临界温差 ,从而改善其抗热震性能 .

The Ta-10W alloy films on P30CrNi2MoVA have been deposited by R. F sputtering technique. The relationships between deposition rate,coating fracture cross sections and deposition conditions have been carefully investigated by SEM and so on.Results indicate that the deposition rate increases linearly with power and nonlinearly with pressure,decreases with substrate bias.The transition zone of tightly packed fibrous grains would change to rough tepered crystallites separated by voids. Higher the pressure. rougher the fracture cross sections. No significant power influence was found on the fracture cross sections,but significant bias influence was done.The fracture cross sections become dense and fined under bias.

利用RF溅射技术在PCrNi2MoVA基上沉积Ta-10W合金薄膜,利用扫描电镜等分析手段研究了薄膜的沉积速率、断口的组织形貌与沉积参数之间的关系。结果表明,沉积速率随功率的增加而线性增加,随Ar气压强的增加呈非线性增加,基底无论加正偏压还是加负偏压都使沉积速率下降。薄膜的组织形貌随Ar气压强的增加由纤维组织变为粗大锥状晶。气压越高,组织越粗大,孔洞尺寸也越大。基底加偏压使组织细化。

Since the components in ZrO 2 NiCoCrAlY graded coating distribute gradually along the direction of thickness,the adherent strength of coating and the coherent strength between coating and substrate are improved,and the thermal shock property of the graded coating is superior to that of the duplex coating.Under the condition of greater thermal shock stress,the coating spalls integrally from the surface of Ti 6Al 4V substrate;Under the condition of weaker thermal shock stress,the...

Since the components in ZrO 2 NiCoCrAlY graded coating distribute gradually along the direction of thickness,the adherent strength of coating and the coherent strength between coating and substrate are improved,and the thermal shock property of the graded coating is superior to that of the duplex coating.Under the condition of greater thermal shock stress,the coating spalls integrally from the surface of Ti 6Al 4V substrate;Under the condition of weaker thermal shock stress,the coating fractures and spalls partly from the surface of the substrate.

ZrO2-NiCoCrAlY梯度涂层的成分沿厚度方向呈连续梯度化分布,提高了涂层与基体的粘结强度和涂层的内聚强度,其抗热震性能优于双层涂层。在较大热冲击应力作用下,梯度涂层整体自基体表面剥落而失效;在较小热冲击应力作用下,由于NiCoCrAlY底层与TC4合金基体发生了热相互作用,改善了涂层与基体的结合状况,梯度涂层纵向断裂并部分自基体表面剥落而失效。

The mechanical properties and wear resistance of the coatings were examined with a nano indentor equipped with an optical microscope and an atomic force microscope as the attachments. It has been found that a step appears on the loading force displacement curves at the onset of coating fracture and a straight line segment...

Coatings of TiN, TiN/Ti(C,N)/TiC, TiN/Ti(C,N)/TiC/Ti(C,N)/TiC and TiN/Ti(C,N)/TiC/Ti(C,N)/TiC/ Ti(C,N)/TiC were prepared on cemented carbide substrate by chemical vapor deposition (CVD). The mechanical properties and wear resistance of the coatings were examined with a nano indentor equipped with an optical microscope and an atomic force microscope as the attachments. It has been found that a step appears on the loading force displacement curves at the onset of coating fracture and a straight line segment appears on the loading force square of indented depth curves, the latter could be used to identify the interfacial failure of the coatings. The crifical load p f and p i was proposed to be used to describe the fracture failure and the interfacial failure of the coatings, respectively. Generally speaking, multi layer coatings have better mechanical properties and higher wear resistance than the mono layer counterpart. With increasing in the layer number, the fracture toughness and wear resistance of the multi layer coatings increase as well.
