Summary
Laser induced breakdown spectroscopy (LIBS) enables real-time elemental analysis during additive manufacturing. This technique accurately quantifies key components and detects production failures in wear-resistant coatings.
Area of Science:
- Materials Science
- Analytical Chemistry
- Manufacturing Engineering
Background:
- Additive manufacturing, specifically direct energy deposition, requires precise control over material composition.
- Real-time monitoring of elemental composition is crucial for ensuring the quality of high-wear-resistant coatings.
- Traditional offline analysis methods do not provide immediate feedback during the manufacturing process.
Purpose of the Study:
- To demonstrate the feasibility of in situ quantitative multielemental analysis using laser induced breakdown spectroscopy (LIBS) during direct energy deposition.
- To assess the capability of LIBS for detecting production failures in real-time.
- To evaluate the impact of LIBS sampling on the additive manufacturing process and the resulting clad properties.
Main Methods:
- Development of a compact LIBS probe integrated with an industrial robot and laser cladding head.
- In situ quantitative elemental analysis of nickel (Ni) and tungsten (W) in nickel alloy coatings reinforced with tungsten carbide particles.
- Comparison of LIBS results with offline measurements using electron energy dispersive X-ray spectroscopy (EDS) and X-ray fluorescence spectroscopy (XRF).
- Microscopic analysis (optical and scanning electron microscopy) to assess the impact of LIBS on the cladding process and clad properties.
Main Results:
- Successful demonstration of in situ quantitative elemental analysis of Ni and W during the cladding process.
- LIBS analysis results showed good agreement with offline EDS and XRF measurements.
- No significant impact of LIBS sampling on the cladding process or the properties of the resulting clad was observed.
- LIBS effectively detected process failures such as poor laser beam quality and undesirable variations in component concentrations.
Conclusions:
- Laser induced breakdown spectroscopy (LIBS) is a feasible technique for in situ quantitative elemental analysis during direct energy deposition in additive manufacturing.
- LIBS serves as a valuable tool for real-time monitoring and detection of production failures, enhancing quality control.
- The integration of LIBS does not negatively affect the additive manufacturing process or the quality of the produced coatings.

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

01:27Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
4.3K
α,β-Unsaturated carbonyl compounds with two electrophilic sites, the carbonyl carbon, and the β carbon, are susceptible to nucleophilic attack via two modes: conjugate or 1,4-addition and direct or 1,2-addition.
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...

Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...

58.9K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
