“…Furthermore, its more ductile FCC structure also leads to the improvement of cemented carbide fracture toughness. The principal difference between them is the higher stacking fault energy of Ni that results in lower hardening rates [6][7][8][9][10][11][12][13][14][15].…”

“…Several methods for experimental testing of tribology and wear behavior of potential roll and cladding materials have been used by researchers. The majority of these methods can be roughly classified as 1) pin‐on‐disc or ball‐on‐disc tests, 2) ring‐on‐bock tests with different setups, 3) block‐on‐disc tests with or without addition of abrasive particles, and 4) disc‐on‐disc or roll‐on‐roll tests with two or even three discs or rolls, respectively. Among those test methods, in particular, the roll‐on‐roll tests are suitable to simulate the combined effects of relative motion (slip effects) and high contact pressure between the rolls of the rolling mill and the metal strip.…”

“…MMC claddings typically consist of crushed or spherical tungsten carbide particles embedded into an iron‐, cobalt‐, or nickel‐based matrix. The microstructure and the wear behavior of these claddings are generally well studied at room temperature, but only a few investigations focus on their particular wear behavior at elevated temperatures . At room temperature, abrasive wear tends to decrease with increasing hardness of the MMC cladding, i.e., with increasing content or size of the hard particles inside the matrix, respectively.…”

Laser metal deposition (LMD) is utilized to clad the surface of a miniaturized test roll (Ø 40 mm) of tool steel. The cladding consists of two layers: a nickel alloy as intermediate layer deposited onto the surface of the steel substrate, and a metal matrix composite (MMC) as top layer consisting of spherical tungsten carbide particles embedded into the nickel alloy matrix. The thermomechanical wear behavior of the cladding is investigated on a test rig, where the test roll is pressed against an inductively heated load roll. Multiple test runs up to several hours simulating industrial loading conditions are performed. The presented testing procedure enables predicting the time-dependent abrasive wear behavior of the cladding, in particular for hot rolling mill applications. After testing for 8 h at temperature of 650 C and at contact pressure of approximately 1 GPa, the maximum depth of the wear mark is about 0.12 mm. Partial cracking, debonding and dissolution of the tungsten carbide particles, as well as formation of iron and chromium oxides at the surface of the wear marks occur. However, as low abrasive wear is observed, the investigated MMC may potentially be applicable for cladding rolls in steel hot rolling mills.

“…The high-power laser beam melts the cladding material and the substrate surface to form a metallurgical bond [4,5]. The protecting layer exhibits excellent corrosion and wear resistance for complex working environments [6][7][8]. Compared with traditional surface modification techniques, such as thermal spraying, physical vapor deposition, and chemical vapor deposition, coatings deposited by laser cladding possess many superior characteristics, such as a lower dilution rate, higher density, and a lower number of pores [9,10].…”

In order to better understand how a high energy input and a fast cooling rate affect the geometric morphology and microstructure of laser cladding aluminum composite coatings, a three-dimensional (3D) transient finite element model (FEM) has been established to study the temperature field evolution during laser cladding of AlSiTiNi coatings on a 304 stainless steel substrate. In this model, a planar Gauss heat source and a temperature selection judgment mechanism are used to simulate the melting and solidification process as well as the geometric morphology of the laser cladding coatings. The differences in physical characteristics of the cladding materials before and after melting are considered. The results of thermal simulations, including temperature history, temperature gradient, and solidification rate, of the laser cladding coatings are investigated. Corresponding experiments, conducted using an IPG-YLS-5000 fiber laser, are used to verify the simulation results. The experimental observations agree well with the theoretical predictions, which indicates that the established model is valid.
