چکیده
Austenitic high-manganese steels (HMnS) offer very high wear resistance under dynamic loading due to their work hardening capacity. However, static abrasive is limited. Various approaches increasing abrasion are known from traditionally manufactured metallurgical components. These confirm the potential for surface protection applications. In this work, powder of Hadfield HMnS X120Mn12 prepared and processed by high-velocity oxy-fuel (HVOF) spraying spark-plasma sintering (SPS). A good correlation was observed between results HVOF SPS specimen. Different conditions coatings sintered specimens were machining. Compared polished state, turning diamond smoothing can increase hardness 220 HV over 700 significantly. Regardless finish condition, similar be demonstrated strong sliding reciprocating loading. contrast, machining process clearly influences in scratch test with best smoothed condition. Especially against background current trends toward alternative coating systems, presented a promising approach development field technology.

متن کاملSpark Plasma Sintered Hydroxyapatite – Zirconia Composites: Structural and Mechanical Properties
Hydroxyapatite (Ca10(PO4)6(OH)2) (HAp) is a very attractive material for human tissue implantation, beacuse it makes up ~69% of the weight of bone [1]. Unfortunately HAp posses low mechanical properties (strength, fracture toughness), which is a barrier to its applications in load-bearing situations [2]. The mechanical properties of HAp composites, is based on the synthesis of composites and th...
