Then, the factors affecting the quality of coating should be analyzed.
TiO2 has high melting point and mechanical strength.
Factors affecting the quality of coatings During the exploration of fabricating thick ceramic coatings, it was found that the spraying parameters, spraying powders’ characteristic and morphology and the substrates’ conditions all affected the adhesion and quality of the coatings.
It showed that deposition efficiency relied on gas temperature, powders’ properties and especially, the substrates’ ductility.
The ductility could affected the deposition of second pass.

A number of factors considered important in controlling the properties of steel products and affecting the residual manganese in the basic Oxygen furnace (BOF) have been investigated by changing some industrial parameters, aiming at optimizing the residual manganese in BOF.
The studied factors were manganese oxide in the slag, iron oxide in the slag, tapping temperature, Slag basicity, Lance height, blowing time, and carbon content.
In order to study the behavior of manganese oxidation, the factors affecting the residual manganese were studied at the end of the blow.
The parameters affecting on the residual manganese during steel making process in basic oxygen furnace BOF was investigated, 2.

The other morphological parameters also affect the mechanical response, but to a smaller degree.
Earlier we have studied the mechanical properties [5] and the crack formation and propagation phenomena in PLCs [6].
The morphology of the material was also shown to affect its properties [8].
Thus, this parameter seems to have only a minor effect on properties.
The employed methodology has demonstrated its potential for prediction of mechanical properties.

Predicting the material's mechanical properties is essential for reducing testing time, cost, and effort.
Introduction Aluminum is the most used nonferrous metal in the local and global industries due to its excellent physical properties, and the wide range of mechanical properties that it attains through heat treatment and alloying [1].
Despite the well-defined steps in the T6 treatment, various factors affect the achieved values of mechanical properties such as hardness and impact toughness.
Their result showed that mechanical properties were not affected during artificial ageing by the prior precipitation process.

When air cooling is applied the structure radically changes and at the same time the mechanical properties of the steel.
The highest effect of the cooling rate on the mechanical properties has a simple explanation.
The resulting mechanical properties of the Nb and V-bearing steels with the different cooling rates are presented in Table 3.

The Effect of Partial Pressure of Nitrogen on Coating Properties The difference between nitrogen partial pressure and other influencing factors is that it is one of the constituents of nitrogen-based coatings.
Due to the fact that it can change the composition of nitrogen in nitrogen-based coatings, the influence of nitrogen partial pressure affects their phase composition and tissue properties.
However, it is vital to find the process parameters for a coating preparation by combining various influencing factors, researchers need to optimize them through computer simulations or experiments.

This "partial" crystallization has a subsequent influence on magnetic and thermal properties of ball-milled powders and thus, it can also influence the properties of the final compacted samples.

To fulfill large bone defects requirements, the ideal biomaterial should combine interconnected porosity, sufficient mechanical strength according to the implantation site, and angiogenic factors release ability.
Mechanical properties evaluation.
A minimal content of 0.3% of apatite appeared necessary to obtain scaffolds with improved mechanical properties.
Mechanical resistance is another critical parameter affecting the implantability of the final device and its in vivo fate.
We show here that apatite addition can improve mechanical properties of the scaffolds without affecting interconnected porosity.
