Characteristics of the raw materials.
The requirement of lighter materials with high specific strength and stiffness has led to the development of a wide range of MMCs as an alternative to the conventional engineering alloys and the research on the ceramic reinforced MMCs has increased significantly.
It can be seen how elevated TiCN quantities avoid Cu diffusion, which would affect to materials densification.

Failure of heat exchanger tubes in coal-fired boilers has become a key material issue in the design and operation of thermal power plants and is recognized as being one of the main causes of downtime in these installations [6-8].
Therefore, the development of wear and high-temperature oxidation protection systems for industrial boilers is a very important topic from both engineering and economic perspective [6].
This technique provides higher kinetic energy of the particulates and lower melting coating materials that enable particle-flattening in the plastic state [14].
Materials The substrate material selected for the study was T91boiler tube steel.

The system combines advanced 3G data transmission,professional engineer support in the remote background with collecting information ,it is greatly improved.
As the literature [8] 3.2 The design of navigation algorithm Generally the power grid is a tree structure, with both ring and network structure, so route selection is particularly important thing,bacause a reasonable route choice could shorten the repair time and be convenient deployment of human and material resources to improve the reliability .
Step four: base the order that after the weighted, combination of the polygon, and according the polygon overlay,balance weight ratio,take a combination of at least duplicate lines, is the optimization model of path, the key point is to control the size of the polygon,we seem weight value in the same line as the basis,with a minimum area of polygon as the core,to do the calculation on the adjacent polygons, comparison showed that the total line length, finding optimal path.

Introduction The iron and steel industry is the important foundation of social development, total production of steel 10 times growth to support the sustained and stable growth of GDP in recent 30 years.China, EU, USA and Japan in recent years was released in 2020 of steel industry technology development guide also emphasize,steel is still the human social irreplaceable functional, structural base material in the predictable inside quite long period of time.Iron ore is the source of Iron and steel industry, have industry to use value of iron ore are mainly magnetite, ilmenite, hematite, limonite and siderite in the current technical conditions.The rapid reduction of magnetite ore reserves,therefore we must study the reasonable process to develop huge reserves and quite of hematite.
Slon series centrifuge of pneumatic control discharge product by the Ganzhou circle magnetic separation equipment company,has been completely solve the problem of centrifugal separator the channeling of concentrate and tailings.Such as Yang Qinglin Engineer of Ganzhou circle magnetic separation equipment limited company on sea steel red tailings of iron ore tailings(iron tailings average grade of 28.12% ) " strong magnetic centrifugal process"to obtain the final iron concentrate 61.30%, with yields of 8.5% and recovery 18.53% in the industrial recovery of fine hematite tailings test;Gao Shuling in a Anshan type lean hematite ore beneficiation process, using SLon -750 vertical ring pulsating high gradient magnetic separator on high intensity magnetic separation with hydrocyclone overflow and spiral chute tailings.Iron grade is improved from 17.24% to 35.45% after high intensity magnetic separation, to further gain high grade concentrate laid a good foundation by reverse flotation;Iron grade
In China 's iron ore resources nervous,the new processing equipment and new drug development is unusually rapid today,accelerate the use of our country did not use the mineral resources step is very important. 2) Accelerate fine hematite beneficiation technology research.At present,our country has not been fully utilized hematite is the main cause of fine hematite ore difficult to obtain good separation indexes.Magnetic separation-anionic reverse flotation process although in some hematite ore in the implementation of the indicators of the historic breakthrough, but for the finer iron ore beneficiation indexes are still not high.How to study new technology to realize our country fine red iron ore beneficiation technology breakthrough is the key of further use of China's hematite resource . 3) Strengthen the hematite beneficiation equipment research.In hematite beneficiation equipment research,one hand should continue to improve is now in hematite plant equipment performance, make
