This research narrows the control factors to droplet size and scanning pattern while keeping the rest at reasonable levels so that the printing process is robust and the result is repeatable.
Given these factors are correctly settled, a bipolar waveform sent to the piezo actuator for triggering is very important in controlling the droplet formability, size, ejection velocity and repeatability.
The result also shows the factors of pitch and hatch have a significant control of the layer thickness which could be varied between 13 to 60 microns.
And the layerthickness will further affect the surface roughness.

Like this study, even though oxygen dissolved in the solution was not considered, elevating the temperature of NaCl solution, viscosity of the solution is decreased, but on the other hand, activity of the ion that is a corrosion factor is increased.
Therefore, corrosion degradation of the specimen is promoted due to the instability of oxide film on the surface of the material as well as the penetration effect of the corrosion factors.
Since the asperity and oily particles on the surface of the specimen affect corrosion reaction of metal, after polishing the surface of every specimen, then cleaned with the ultrasound washer.

As we all know that, the smooth of the railway is the main factor to influence and control the speed of traffic [1].
Normalizing treatment after welding had played an important role in refining grain size to the weld regions and base metal, and the mechanical properties of the material had been improved.
However, the HAZ area which carried on normalizing treatment and stress relief annealing, the hardness of which were smaller than that of welding condition, especially after stress relief annealing, the hardness dropped 57HV.By comparing the three kinds of heat treatment condition hardness distribution in Fig. 3 could be seen that, normalizing treatment made the weld regions and basic material mechanical properties improve, and stress relief annealing made the joint mechanical properties decline.
(2) Normalizing treatment and stress relief annealing were carried on the welded joint, the results showed that normalizing treatment can improve the mechanical property of weld joint.
However stress relief annealing made the joint mechanical properties decline.

Introduction One of the main features of modern high technologies is the desire to create and use new materials that have, in addition to a unique combination of mechanical, physical, and other properties, the ability to actively respond to changes in external conditions or external influence (smart materials).
The aim of this work is to study the regularities of formation of nanostructured surface layers of materials based on Ti50Ni48.5Co1.5 diffusion metallization of mechanically activated powder and subsequent thermomechanical treatment for functional and mechanical properties.
Summary The studies found that the formation of surface-modified layers of materials with SME by a complex method, comprising diffusion metallization of mechanically activated powders based on Ti50Ni48.5Co1.5 – coated steel 3 with subsequent thermomechanical treatment, allowed a nanostructured state to form in the surface layers with increased functional, mechanical, and performance properties.

The aluminium bronze alloys with aluminium content above 9 wt% and addition of nickel and iron allow high mechanical resistance by heat treatment, causing them to be preferred in the manufacture of components where good combination of mechanical, wear and corrosion resistance is required.
This phenomenon affects the tool rake face by changing the cutting geometry and consequently the workpiece surface finishing [8].
Li et al. [8] studied the adhesion of material on the carbide insert and high speed ​​steel (HSS) in the bronze-aluminum machining, and they found that the distribution of higher adhesion points depends on factors such as temperature and pressure.
This behavior affected the surface roughness result; · The low abrasion wear affected only the coating of inserts.

Analysis of the influence factor on the silt deposition and PSO-SVM algorithm 2.1 Analysis of the influence factor on the silt deposition 2.1.1 Mechanism analysis of the silt deposition To the harbor channel outside the sea or river, the sand brought by wind and wave could be classified as bed sand and floating sand.
Consider there are so many factors in the formation of the channel silt, a predictive model of the channel silt was established by using PSO-SVM algorithm.
The optimum solution was obtained by using PSO-SVM to firstly set every factor which could affect the channel siltation to be the related particle’s position vector (X), and then use mean square error energy function to be the optimized target function, and then iterated through the particle swarm optimizing equation 7 and 8.

Introduction In the analysis of rock slope stability, structural plane has become recognized as the main control factor.
The above structural planes were further split under the influence of unloading in the excavation and construction blasting, slope rock mass engineering properties become worse.
The survey found that different causes of the structural planes in the slope is the main factor to influence the slope stability, the mechanical strength of the structural planes and its relationship with space become the main content.
Characteristics and Types of Structural Planes in Lugu Granite From the point of view of the structural plane shear strength, do not consider the structural plane causes here, mainly based on the spatial morphology, roughness and filling mud which are the main factors affecting the shear strength.

Therefore, the properties of metal matrix and its diamond retention capacity are key factors in governing the performance and useful life of the tools [1,2].
Alloying is an effective method to improve the properties of metal materials and has been widely used for many decades in the materials produced by fusion metallurgy.
Effects of some elements, such as Cr, Co, Ni, Mn and Al on the mechanical properties of both compact and porous metal- bonded diamond composites have been published in our previous report [7].
However, as it was presented in our previous report [7], the addition of Cr, Co, Ni, Mn, Al did not bring much positive effect on the mechanical properties of metal bonds or diamond composites.
Though the addition of Cr or Co seems to have no obvious effects on improving the mechanical properties of metal bonds and diamond composites, stronger bonding between the meal bond and diamond grit was obtained by the tightly attached of the metal bond with diamond grit as shown in Fig.5 and Fig.6.
