By using a reciprocating sliding wear test machine,friction and wear behaviors of four types of dental resin composites opposite to TA2 pure titanium were investigated and compared under the lubrication of artificial saliva.

Taking the titanium TA2 pipeline welding of a 1×104 t/a caustic soda equipment with ionic membrane in a Qinghai company for example,this paper expatiates on the features and weldability of TA2 material,details its welding method,welding material selection,groove form,welding process parameters,operation skill and quality control,and points out matters for attention.
