The Bridge | Materials Analysis eNewsletter

SEPTEMBER 2021, ISSUE 99

WELCOME

This month, The Bridge has a specific emphasis on metals and alloys, as well as an introduction to the popular Thanh and Glenn Show (#TandGShow ), social media postings that cover useful XRF topics in a video format. In addition, the Summer 2021 edition of the Rigaku Journal has been released and there are links to the articles at the end of the newsletter.

Quality production demands control of material properties throughout the entire process, from raw material to finished product. The speed and precision of X-ray fluorescence (XRF) elemental analysis make it a preferred testing method in high sample throughput chemical analysis. In addition to alloy stoichiometry, X-ray diffraction (XRD) examines phase composition, retained austenite concentration or residual stress, which correlate with structural quality of your products. Within a very few seconds, the Rigaku KT-100S handheld metal analyzer easily performs identification of the most difficult alloy grades. The device utilizes laser induced breakdown spectroscopy (LIBS), enabling durable and accurate alloy identification for metal sorting, quality assurance and positive material identification (PMI) in mission-critical operations.

The Thanh and Glen Show (#TandGShow ) links all Rigaku Americas Corporation WDXRF posts to one specific page on LinkedIn. Cohosts Thanh Nguyen (Sr. XRF Application Scientist) and Glenn Williams (Analytical Services Mgr.) provide useful information about interesting XRF applications in an entertaining format.

UPCOMING EVENT

Rigaku Workshop at Gulf Coast Conference

Oil Sample Solidification: A Unique Approach to XRF Analysis of Petroleum-Based Samples
Currently Scheduled: 10/12/2021 - 2:00 PM - 3:00 PM
Main Author: Glenn Williams, Rigaku Americas Corporation

Additional Authors: Thanh Nguyen, Rigaku Americas Corporation

Abstract:

Three significant challenges to the traditional thin film sample cups used in direct X-ray fluorescence (XRF) oil analyses are: 1) leakage that can occur during either analysis or in queue before or after analyses, 2) key analyte settling that can give rise to higher or lower than nominal values, and 3) the inability or reduced sensitivity that this preparation technique affords the analysis of light element analytes. Oil solidification sample prep techniques provide a potential solution to all these challenges, as well as providing additional benefits. This training session will provide live hands-on demonstrations of solidification and analyses of a variety of petroleum-based oils as well as examples and comparisons of the analytical results.

FEATURED APPLICATION NOTES

Phosphorous on Steel

Applied Rigaku Technologies

Aluminum and steel are often coated with a protective conversion coating, also called passivate or passivation coating, to prevent oxidation and corrosion of the base metal. Conversion coatings include Cr, Ti, V, Mn, Ni, P or Zr. A phosphate coating may be applied as to minimize wear on cutting tools and stamping machines. Aluminum is often coated for use in aircraft parts, aluminum window frames and other similar industries where the aluminum is exposed to weathering. Steel for the automotive industry is typically first galvanized with a zinc coating before the conversion coating is applied. Protected steel is also used for outdoor sheds and other similar uses where steel is exposed to weathering. Conversion coating also help in the retention of paint for the final finished product.

In this application note, the measurement of phosphorus (P) conversion coating on galvanized steel is demonstrated using a Rigaku NEX QC+, EDXRF spectrometer.

Accurate Quantitative Analysis of Ferrosilicon by the Fusion Method Using ZSX Primus III+

Rigaku Corporation

Ferrosilicon is one of the most basic materials used in the steel making process. Iron alloys with silicon content between 15% and 90% are called "ferrosilicon," and are used in the reduction of the iron, removing oxygen and adding silicon when cast iron or steel alloys are produced. As part of controlling the steel making process, analyses of slag and raw materials such as quicklime are also required. X-ray fluorescence spectrometers are the most common analysis tools to analyze ferroalloy, slag, steel and added materials owing to the rapid analysis and the ability to measure both bulk metal and powders. This application note describes accurate ferrosilicon analysis using ZSX Primus III+, which is optimized for process control of steel making and ferrosilicon production.

Solving Carbon Equivalence with Handheld LIBS

Rigaku Analytical Devices

It is critically important to ensure the right grade of steel is being used for an application. However, being dependent on the grade alone can be a risk, as there can be significant variations even within a grade. Problems with weld integrity can occur due to variances in the exact composition. Variances in metal alloy grades happen because of secondary production of metal alloys from recycled materials produced in an electric furnace. Secondary production introduces residual elements to the process. These residual elements typically include vanadium (V), manganese (Mn), chromium (Cr), molybdenum (Mo), copper (Cu), and nickel (Ni). This means precise measurements of the exact composition of each individual piece are necessary to determine how the component will behave.
