Although other researchers also mentioned the thermal effects to the wear of diamond grains in processing granite materials [4-5], enough direct evidence has not been found until now.
The depth below the surface for each grinding pass was calculated as the product of the number of passes before the final one and the wheel depth of cut.

The thickness of the coating material may be regulated in this approach by choosing the appropriate number of dips of the substrate in the suitable solvent [16].
According to the AFM assay's colour spectrum, the dominant particle rate in the sample varies between 50 and 200 nm with a grain size range of 20 to 40, the distribution of larger particles scales proportionally down the curve.

A number of metavolcanic rocks have been reported to contain tuffaceous and glassy materials associated with the basement complex in Sinai and the Eastern Desert of Egypt [17,19].
The variation in setting times may be caused by a reduction in the rate of the procedure of hydration, where a portion of the water required for cement setting is used by the Pozzolan, or by the dilution produced by the cement grains [31].

The stiffening behavior and the grain structure of the grout has to facilitate the bedding and fixing of the concrete segments, thus decreasing the settlement of existing tunnels.

It was reported that the addition of Ca into zinc phosphate coating enhanced the corrosion resistance of AZ31 alloy due to the fine-grained structure of Zn-Ca-P coating [17].
Sr doped ZCP coated sample showed highest number of viable cells of all other substrates due to the chemical stability of the coating. 4.

Increase in weight % of particle reinforcement decreases with the grain size [3].
The reinforcement particles produce huge sizes of dislocation density during the solidification of Aluminium Metal Matrix Composite (AMMC), which produces additional resistance to plastic deformation, thus enhancing hardness number [2, 5].

Fig. 5 summarizes the AE count numbers detected when the C2S-CZ and 8YZ coatings were heated and cooled.
Moreover, few horizontal micro-cracks exist at the grain boundary, suggesting that the adhesion between each particle is a strong bonding.

A number of advantages occur for composites.

Rice straw waste is obtained after threshing rice grains from rice stalks, rice husk waste is obtained after the milling process, and the rice is separated from the outer shell.
The number of catalysts used in this study was 2% of the total matrix volume.

The main dependencies and functions are well-known for a number of technically relevant polymer compounds and composites.
