For this reason, the wear development is investigated for samples alloyed with different materials with a modified pin-on-disc test.
Experimental Setup and Materials In this study, the characterization of the wear behavior was performed with a modified pin-on-disc test.
In Table 1 the chemical composition of the used materials are presented.
A significant increase in the adhesive wear resistance could not be achieved by using the filler wire materials NiMoCr90 and 308L.

Key words: TOFD; Weld detection; Thick wall tube welding; ultrasonic; scanning
Abstract: This article firstly introduces the ultrasonic TOFD (Time-of-flight - Diffraction) detection technology of detection principle, advantages and disadvantages, and then summarizes the ultrasonic TOFD technique related testing standard, finally combining the reality of tube mill, analyses the pipe material testing near the surface of the blind area and radian impact
A) scans near surface defects B) wall not fusion defect scan C) slag defect scan D) hole defect scan Figure 6 Weld defect inspection record legend TOFD detection technology Chinese special equipment inspection research center in China in the national "five-year" science and technology research plan was carried out by ultrasonic endpoint diffraction technology research, and develop special focusing probe, measuring accuracy of the height of defects of 0.5 mm.
With phased array TOFD method, do not need to adjust the probe position, can change detection Angle and focus depth, so easily according to the thickness, material quality and standard requirements, selected the best testing conditions. 3.2 radian pipe problem Due to tube inevitably has the curvature, considering the probe mechanical structure layout, small diameter, wall thickness, thin tube, the probe spacing not less, when the probe span is more than twice the wall thickness, will lead to accept the probe signal analysis is relatively complex.
At present HFW pipe diameter from 219 mm to 610 mm, wall thickness from 4.0 mm to 4.0 mm, can be used to do the test material.Finishing the weld ultrasonic coupling channel by finding a way.

Introduction
Metal nanoparticles (NPs) are applied in several fields of biotechnology, nanobiotechnology, material science, medicine, etc. [1].
Methods and Materials Plant sampling, identification and extraction procedure Arial parts of S. suffruticosa were collected from Lalehzar Mountain (40R05435550, UTM3327896) in Kerman Province in 2018.
In comparison with bulk parental materials, NPs such as AgNPs have unique physiochemical properties such as size and shape (1–100 nm diameter) and greater surface area to volume ratio that lead to the higher chemical reactivity of these NPs [39].
